Description
본 발명은 액정 디스플레이 패널에 관한 것으로, 보다 상세하게 실링제에 광차단 역할을 부여하여 패널의 안정성을 유지하면서 패널 주변부의 빛샘을 제거할 수 있도록 한 액정 디스플레이 패널에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display panel, and more particularly, to a liquid crystal display panel in which the sealing agent is provided with a light blocking role to remove light leakage around the panel while maintaining the stability of the panel.
주지된 바와 같이, 일반적으로 박막 액정 디스플레이(LCD; Liquid Crystal Display)는 휴대형 단말기기의 정보 표시창, 노트북 PC의 화면표시기, 랩탑 컴퓨터의 모니터 등의 정보표시장치로 사용되고 있다. 특히, 액정 디스플레이는 기존의 브라운관형 모니터(CRT)를 대체할 수 있는 디스플레이장치로 산업상 그 활용도는 매우 높다.As is well known, a liquid crystal display (LCD) is generally used as an information display device such as an information display window of a portable terminal device, a screen display of a notebook PC, a monitor of a laptop computer, and the like. In particular, the liquid crystal display is a display device that can replace the conventional CRT monitor, the industrial use is very high.
그러한 박막 트랜지스터-액정 디스플레이 패널을 제작하는 공정에서는 기판의 합착을 위한 실(Seal)이 제공되는 바, 그 실(Seal)은 어레이 기판과 컬러필터 기판(이후 C/F)을 합착하여 LCD의 형태를 만들고, 기판과 기판사이의 밀폐된 공간을 유지하여 액정이 들어갈 수 있게 하는 중요한 자재이다.In the process of manufacturing such a thin film transistor-liquid crystal display panel, a seal is provided for bonding the substrate, and the seal is formed by bonding the array substrate and the color filter substrate (hereinafter, C / F) together. It is an important material to make the liquid crystal enters to maintain the closed space between the substrate and the substrate.
도 1a, 1b, 1c, 1d는 종래의 박막 트랜지스터-액정 디스플레이 패널을 나타내는 측면도이다.1A, 1B, 1C, and 1D are side views illustrating a conventional thin film transistor-liquid crystal display panel.
이를 참조하면, TFT 어레이 기판(2)의 상부에 일정거리 이격된 상태로 컬러필터 기판(4)이 구비되며, 그 컬러필터 기판(4)의 하면에는 블랙 매트릭스(6)가 광차단을 위하여 구성된다. 그리고, 상기 TFT 어레이 기판(2)과 컬러필터 기판(4)의 가장자리 소정부에는 그 기판(2, 4)을 부착시키고 그 내부에 액정을 구성하기 위한 실(Seal; 8)이 구비된다.Referring to this, the color filter substrate 4 is provided on the TFT array substrate 2 with a predetermined distance spaced apart, and a black matrix 6 is formed on the bottom surface of the color filter substrate 4 for light blocking. do. A predetermined edge portion of the TFT array substrate 2 and the color filter substrate 4 is provided with a seal 8 for attaching the substrates 2 and 4 and for forming a liquid crystal therein.
상기 실(Seal; 8)에 요구되는 조건은 두 글라스 기판(2, 4)을 단단하게 합착, 유지하는 능력이며, 컬러필터(4)의 역할은 화면이 되는 액티브 영역에서는 어레이와 액정에 의해서 제어되는 빛에 색깔을 띄게 하고, 그 외부분, 특히 LCD 패널의 주변부에서는 원치 않은 빛이 새지 않도록 차단한다. 컬러필터에서 빛을 차단하는 부분은 검정색으로 패터닝되어 있고 이 부분을 블랙 매트릭스(6)라 한다.The condition required for the seal 8 is the ability to firmly bond and hold the two glass substrates 2 and 4, and the role of the color filter 4 is controlled by the array and the liquid crystal in the active area of the screen. It makes the light become colored, and blocks the outside light, especially unwanted light from the periphery of the LCD panel. The light blocking portion of the color filter is patterned in black, which is called a black matrix (6).
그러나, 패널 주변부에서 블랙 매트릭스(6)의 빛 차단에는 한계가 있어서, LCD 모듈을 만들 때 차광 테잎이라는 광차단제를 부착하게 된다. 블랙 매트릭스(6)가 빛을 완전하게 차단하지 못하는 이유는 블랙 매트릭스(6)를 글라스 끝단까지 충분히 확장해서 만들지 못하기 때문이다.However, there is a limit in blocking light of the black matrix 6 at the periphery of the panel, so that a light blocking agent called a light shielding tape is attached when the LCD module is made. The reason why the black matrix 6 does not completely block light is that the black matrix 6 cannot be made to extend sufficiently to the glass edge.
블랙 매트릭스(6)를 글라스 끝단까지 확장하지 못하는 이유는 블랙 매트릭스(6)의 재질에 따라 크게 두가지를 들 수 있다. 첫째로, 블랙 매트릭스(6)가 크롬 재질인 경우에는(도 1a, 1b참조) 단면이 노출된 크롬이 수분과 반응하여 부식을 일으키거나, 패드부와 전기적 단락(단락, 합선)을 일으키기 때문이다. 두 번째로, 블랙 매트릭스가 수지(유기화합물; 도 1c, 1d 참조)재질인 경우에는 수지 블랙 매트릭스(6')의 글라스(2, 4)와의 접착력이 그리 좋지 못하므로 패널을 합착, 유지하는 데에 문제가 생기게 된다.There are two main reasons for the black matrix 6 not extending to the glass end, depending on the material of the black matrix 6. First, when the black matrix 6 is made of chromium (see FIGS. 1A and 1B), the exposed chromium reacts with water to cause corrosion or to cause an electrical short circuit (short circuit or short circuit) with the pad part. . Second, when the black matrix is made of a resin (organic compound; see FIGS. 1C and 1D), the adhesion of the resin black matrix 6 'to the glass 2 and 4 is not so good. Problems arise.
따라서, 일반적인 셀 설계는 블랙 매트릭스(6, 6)의 끝단이 실(Seal: 8)의 안쪽에 존재하거나, 실(8)에 덮히도록 한다. 패널 바깥쪽 끝단에는 따라서 빛을 그대로 투과시키는 투명한 부분이 필연적으로 존재하며 블랙 매트릭스(6, 6')의 빛 차단에 한계가 있는 것은 이 때문이다.Thus, a general cell design allows the ends of the black matrices 6, 6 to be present inside or covered by the seal 8. Therefore, there is inevitably a transparent part at the outer end of the panel that transmits light as it is, and there is a limit in blocking light of the black matrices 6 and 6 '.
이에 본 발명은 상기한 종래 기술의 사정을 감안하여 이루어진 것으로, 패널의 가장자리 내부에 마련된 실(Seal)이 광을 차단할 수 있도록 함으로써 블랙 매트릭스의 광차단용 보조재로 사용하여 균일한 광차단이 이루어지도록 하는 액정 디스플레이 패널을 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described prior art, and the seal provided inside the edge of the panel can block light so that the light blocking aid can be uniformly used as a light blocking aid of the black matrix. Its purpose is to provide a liquid crystal display panel.

이를 참조하면, 주입구(14) 봉지제인 END 실런트(Sealant: 16)도 빛을 차단하는 기능을 부여하여 주입구(14)측 빛샘을 차단할 수 있으며, 빛샘 차단윈리는 실(Seal: 10, 12, 12')과 동일하다.Referring to this, the END sealant (Sealant 16), which is an encapsulant 14, may also block light leakage by providing a function of blocking light, and the light leakage blocking window may be a seal (Seal: 10, 12, 12). Same as').
상기한 구성의 본 발명의 일실시예에 따른 광차단 SEAL이 구비된 액정 디스플레이 패널의 기능과 작용을 첨부된 도면을 참조하여 상세하게 설명한다.The function and operation of the liquid crystal display panel with light blocking SEAL according to the embodiment of the present invention having the above-described configuration will be described in detail with reference to the accompanying drawings.
먼저, 상기 블랙 매트릭스(6, 6')를 상기 TFT 어레이 기판(2)과 컬러필터 기판(4)과 동일하게 확장하는 것은 종래 기술에서 기술한 바와 같이 불가능하므로, 상기 실(Seal: 10, 12, 12', 16)이 상기 블랙 매트릭스(6)의 광차단 보조역할을 수행할 수 있도록 함으로써, 상기 실(10, 12, 12', 16)이 글라스의 가장 바깥쪽에 실이 빛을 차단할 수 있다면, 블랙 매트릭스(6)를 확장하지 않고도 빛을 차단할 수 있다.First, it is impossible to extend the black matrix 6, 6 'equally to the TFT array substrate 2 and the color filter substrate 4 as described in the prior art, so the seals 10, 12 , 12 ', 16 can perform the light blocking auxiliary role of the black matrix 6, so that the seal 10, 12, 12', 16 can block the light on the outermost side of the glass It is possible to block the light without expanding the black matrix 6.
그로인해, 본 발명에 따라 그 실(Seal)을 패널의 내부에 마련한 액정 디스플레이는 접착력을 최대로 유지하면서 LCD 모듈제작시 추가공정없이 프레임 주변부에서 발생하는 빛을 차단할 수 있어서 고품위의 액정 디스플레이를 제조할 수 있게 된다.Therefore, according to the present invention, the liquid crystal display provided with the seal inside the panel can keep the adhesive force to the maximum and can block the light generated at the periphery of the frame without additional processing during manufacturing the LCD module, thereby producing a high quality liquid crystal display. You can do it.
한편, 본 발명의 실시예에 따른 액정 디스플레이 패널은 단지 상기한 실시예에 한정되는 것이 아니라 그 기술적 요지를 이탈하지 않는 범위내에서 다양한 변경이 가능하다.On the other hand, the liquid crystal display panel according to the embodiment of the present invention is not limited to the above-described embodiment, various modifications are possible within the scope not departing from the technical gist.
상기한 바와 같이, 본 발명에 따른 액정 디스플레이 패널은 실(Seal)에 빛을 차단하는 기능을 부여함으로 접착력을 최대로 유지하면서도 패널 주변부에서의 빛을 완전히 차단하여, 차광 테잎 등의 공정을 없앨 수 있으므로 제조원가절감, 제조공정축소에 기여 할 수 있으며, 제품의 안정성을 높일 수 있다.As described above, the liquid crystal display panel according to the present invention provides a function of blocking light to the seal, thereby completely blocking the light at the periphery of the panel while maintaining the maximum adhesive force, thereby eliminating a process such as light shielding tape. Therefore, it can contribute to reduction of manufacturing cost, reduction of manufacturing process, and increase of product stability.
