Description
본 발명은 디스플레이 소자에 관한 것으로, 특히 유기전계발광소자(Organic Electroluminescence Device) 및 그 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device, and more particularly, to an organic electroluminescence device and a method of manufacturing the same.
최근 표시장치의 대형화에 따라 공간 점유가 적은 평면표시소자의 요구가 증대되고 있는데, 이러한 평면표시소자중 하나로서 전계발광소자가 주목되고 있다.Recently, as the size of the display device increases, the demand for a flat display device having less space occupancy is increasing. As one of the flat display devices, an electroluminescent device is attracting attention.
이 전계발광소자는 사용하는 재료에 따라 무기전계발광소자와 유기전계발광소자로 크게 나뉘어진다.The electroluminescent device is largely divided into an inorganic electroluminescent device and an organic electroluminescent device according to the material used.
무기전계발광소자는 일반적으로 발광부에 높은 전계를 인가하고 전자를 이 높은 전계중에서 가속하여 발광 중심으로 충돌시켜 이에 의해 발광 중심을 여기함으로써 발광하는 소자이다.In general, an inorganic electroluminescent device is a device that emits light by applying a high electric field to a light emitting part, accelerating electrons in the high electric field, and colliding with the light emitting center to thereby excite the light emitting center.
또한, 유기전계발광소자는 전자주입전극(cathode)과 정공주입전극(anode)으로부터 각각 전자와 정공을 발광부내로 주입시켜 주입된 전자와 정공이 결합하여 생성된 엑시톤(exciton)이 여기상태로부터 기저상태로 떨어질 때 발광하는 소자이다.In addition, the organic light emitting device is based on the exciton generated by combining electrons and holes injected by injecting electrons and holes from the electron injection electrode (cathode) and hole injection electrode (anode) into the light emitting unit, respectively. It is a device that emits light when falling into a state.
상기와 같은 동작원리를 갖는 무기전계발광소자는 높은 전계가 필요하기 때문에 구동전압으로서 100~200V의 높은 전압을 필요로 하는 반면에 유기전계발광소자는 5~20V 정도의 낮은 전압으로 구동할 수 있다는 장점이 있어 연구가 활발하게 진행되고 있다.Since the inorganic electroluminescent device having the above operating principle requires a high electric field, a high voltage of 100 to 200 V is required as a driving voltage, whereas the organic electroluminescent device can be driven at a low voltage of about 5 to 20 V. There is an advantage, and research is being actively conducted.
또한, 유기전계발광소자는 넓은 시야각, 고속 응답성, 고 콘트라스트(contrast) 등의 뛰어난 특징을 갖고 있으므로 그래픽 디스플레이 픽셀(pixel), 텔레비젼 영상 디스플레이나 표면광원(surface light source)의 픽셀로서 사용될 수 있으며, 얇고 가벼우며 색감이 좋기 때문에 차세대 평면 디스플레이에 적합한 소자이다.In addition, the organic light emitting display device has excellent features such as wide viewing angle, high speed response and high contrast, so it can be used as a pixel of a graphic display pixel, a television image display or a surface light source. It is thin, light, and has good color, making it suitable for next-generation flat panel displays.
이러한 용도를 갖는 유기전계발광소자에 있어서는 콘트라스트(contrast) 및 휘도가 좋아야 하는데, 기존의 유기전계발광소자는 주간 옥외에서 콘트라스트가 좋지 않았다.In the organic light emitting display device having such a purpose, contrast and brightness should be good, but the conventional organic light emitting display device does not have good contrast outdoors during the day.
그 이유는 소자의 음극이 거울면처럼 외부에서 입사되는 광을 반사하기 때문이었다.The reason is that the cathode of the device reflects light incident from the outside like a mirror surface.
이러한 문제를 해결하기 위하여 종래에는 원편광판(circular polarizer)을 사용하거나 광산란층을 형성하는 방법 등이 제시되었다.In order to solve this problem, a method of using a circular polarizer or forming a light scattering layer has been proposed.
원편광판을 이용하는 방법은 도 1에 도시한 바와 같이, 투명 기판 하부에 원편광판(circular polarizer)을 형성함으로써 음극에 의한 외부 입사광의 반사를 줄였다.In the method using the circularly polarizing plate, as illustrated in FIG. 1, the reflection of external incident light by the cathode is reduced by forming a circular polarizer under the transparent substrate.
즉, 원편광판은 외부에서 내부로 들어오는 광의 편광방향과 내부에서 외부로 나가는 광의 편광방향이 다르기 때문에 완전한 차단은 아니지만 음극에 의한 외부 입사광의 반사를 상당히 줄여주었다.That is, the circularly polarizing plate is not completely blocked, but significantly reduces the reflection of external incident light by the cathode because the polarization direction of the light entering from the outside is different from the polarization direction of the light from the inside to the outside.
그리고, 광산란층을 형성하는 방법은 도 2에 도시된 바와 같이, 투명 기판하부에 광산란층을 형성하여 광을 산란시켜줌으로써 도 1의 방법과 마찬가지로 음극에 의한 외부 입사광의 반사를 줄여주었다.As shown in FIG. 2, the light scattering layer is formed by scattering light by forming a light scattering layer under the transparent substrate, thereby reducing the reflection of external incident light by the cathode as in the method of FIG. 1.
그러나, 상기와 같은 방법들에 있어서 가장 큰 문제는 음극에 의한 외부 입사광의 반사를 크게 줄여줌과 동시에 유기발광층으로부터 외부로 발산되는 빛까지도 상당히 차단한다는데 있다.However, the biggest problem in the above methods is that it significantly reduces the reflection of external incident light by the cathode and at the same time blocks the light emitted from the organic light emitting layer to the outside.
이로 인하여 콘트라스트는 향상되는 반면에 휘도가 감소하게 된다.This improves contrast while reducing brightness.
종래 기술에 따른 유기전계발광소자에 있어서는 다음과 같은 문제점이 있었다.The organic light emitting device according to the prior art has the following problems.
원편광판 및 광산란층을 도입한 기존의 유기전계발광소자에 있어서는 음극에 대한 외부 입사광의 반사를 줄여 콘트라스트를 향상시키지만 그 반면에 유기발광층에서 발산되는 빛도 일부 차단하여 소자의 휘도를 떨어뜨린다.Conventional organic electroluminescent devices incorporating circular polarizers and light scattering layers improve contrast by reducing the reflection of external incident light on the cathode, while reducing the luminance of the devices by blocking some of the light emitted from the organic light emitting layers.
본 발명은 이와 같은 문제를 해결하기 위한 것으로, 간단한 공정을 통해 소자의 휘도를 떨어뜨리지 않으면서 콘트라스트를 향상시키고, 동시에 픽셀간의 절연을 극대화시킬 수 있는 유기전계발광소자 및 그 제조방법을 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and provides an organic light emitting display device and a method of manufacturing the same, which can improve contrast while maximizing insulation between pixels without reducing the brightness of the device through a simple process. There is a purpose.

먼저, 본 발명의 개념은 발광 픽셀들을 제외한 모든 부분에 색이 진하고 전기 절연성이 좋은 블랙매트릭스층을 형성하여 전극에 의한 외부 입사광의 반사를 줄여 소자의 콘트라스트(contrast)를 증대시키고 각 픽셀들을 전기적으로 절연시킬 수 있다는 것이다.First, the concept of the present invention forms a black matrix layer having a dark color and good electrical insulation on all parts except the light emitting pixels to reduce the reflection of external incident light by the electrode, thereby increasing the contrast of the device and electrically It can be insulated.
도 3a 내지 3c는 본 발명에 따른 유기전계발광소자의 제조공정을 보여주는 평면도로서, 도 3a에 도시된 바와 같이, 먼저, 투명기판(11)상에 ITO(Indium Tin Oxide)로 이루어진 다수의 양극(12)을 일정간격으로 형성하고, 발광영역이 될 픽셀(A) 부분을 제외한 전면에 블랙매트릭스층(색이 진한 물질)(13)을 형성한다.3A to 3C are plan views illustrating a manufacturing process of an organic light emitting display device according to the present invention. As shown in FIG. 3A, first, a plurality of anodes made of indium tin oxide (ITO) on a transparent substrate 11 are provided. 12) are formed at regular intervals, and a black matrix layer 13 (dark material) is formed on the entire surface except the pixel A, which is to be the light emitting region.
이때, 이 블랙매트릭스층(13)의 두께는 약 1~107Å이고, 사용되는 물질은 유기물, 무기물, 고분자, 무기물 옥사이드, 상기 무기물과 고분자를 혼합한 물질(예를 들면, 카본 블랙(carbon black)과 고분자 수지를 혼합) 중 어느 하나이거나 또는 그 물질들을 혼합한 혼합물이다.At this time, the thickness of the black matrix layer 13 is about 1 ~ 10 7 Å, and the material used is an organic material, an inorganic material, a polymer, an inorganic oxide, a material in which the inorganic material and the polymer are mixed (for example, carbon black (carbon black) and a polymer resin) or a mixture of materials.
이어, 도 3b에 도시된 바와 같이, 각 픽셀(A)부분 사이의 블랙매트릭스층(13)상에 양극(12)에 대해 수직한 방향으로 격벽(14)들을 형성한다.Subsequently, as shown in FIG. 3B, the partitions 14 are formed on the black matrix layer 13 between the pixel A portions in a direction perpendicular to the anode 12.
여기서, 격벽(14)은 파지티브 포토레지스트(positive photoresist) 또는 네거티브 포토레지스트(negative photoresist)를 사용한다.Here, the partition wall 14 uses a positive photoresist or a negative photoresist.
그리고, 격벽(14)의 폭은 각 픽셀(A)부분 사이의 간격보다 좁게 형성한다.Then, the width of the partition wall 14 is formed to be narrower than the gap between the pixel (A) portion.
이어, 도 3c에 도시한 바와 같이, 격벽(14)을 포함한 전면에 유기전계발광층(15) 및 음극(16)을 순차적으로 형성한다.Subsequently, as shown in FIG. 3C, the organic light emitting layer 15 and the cathode 16 are sequentially formed on the entire surface including the partition 14.
여기서, 각 픽셀(A)의 유기전계발광층(15)과 음극(16)은 각 픽셀(A) 사이의 블랙매트릭스층(13)과 그 위에 형성된 격벽(14)들 의해 전기적으로 절연된다.Here, the organic electroluminescent layer 15 and the cathode 16 of each pixel A are electrically insulated by the black matrix layer 13 between each pixel A and the partitions 14 formed thereon.

It was made.
또한, 이 블랙매트릭스층은 픽셀과 픽셀 사이를 전기적으로 절연시켜 주기도 하므로 각 픽셀 사이의 격벽과 함께 절연효과를 극대화할 수 있다.In addition, the black matrix layer electrically insulates the pixel from the pixel, thereby maximizing the insulation effect with the partition wall between the pixels.
