Description

Self-luminous photosensitive resin composition Color filter and image display device

The present invention relates to a self-luminous photosensitive resin composition, a color filter manufactured using the same, and an image display device.

Recently, the display industry has undergone a drastic change from CRT (cathode ray tube) to flat panel displays typified by PDP (plasma display panel), OLED (organic light emitting diode), LCD (liquid crystal display) and the like. Among them, LCDs are widely used as display devices used in almost all industries, and their application range continues to expand.

As for the LCD, the white light generated by the backlight unit passes through the liquid crystal unit, and the transmittance is adjusted, and the three primary colors transmitted through the red, green, and blue color filters are mixed to achieve full color.

CCFL (Cold Cathode Fluorescent Lamp) can be used as the light source of the backlight unit. However, in this case, the backlight unit must always apply power to the CCFL. A problem arises in power consumption. In addition, compared with conventional CRTs, there are disadvantages such as a color reproduction rate of about 70% and environmental pollution caused by the addition of mercury.

As a substitute for eliminating the above-mentioned problems, a backlight unit using an LED (Light Emitting Diode) has been actively studied.

When LEDs are used in the backlight unit, it exceeds 100% of the color reproduction range specification of the NTSC (National Television System Committee), which can provide consumers with vivid picture quality.

Therefore, in this industry, in order to improve the efficiency of the backlight light source, a method of changing the material and structure of the color filter and the LCD panel has been proposed.

A color filter is formed by applying a dispersion composition containing a pigment or a dye to pixels of various colors through a patterning process. However, such pigments and dyes cause a problem that the transmission efficiency of a backlight light source is reduced. As a result of the aforementioned reduction in transmission efficiency, the color reproducibility of the display device is reduced, and as a result, it is difficult to express a high-quality screen.

The problem of low color reproducibility can be solved by increasing the light efficiency of the color filter. Therefore, it is proposed to increase the thickness of the color filter, and to introduce a color conversion layer (or light conversion layer) in close proximity to the color filter. The way.

In connection with it, Korean Patent Publication No. 2010-0056437 discloses a method in which a color conversion layer is formed on a color filter layer by an inkjet method, the color conversion layer absorbs light of a specific wavelength, and outputs the For light having different wavelengths, Korean Patent Publication No. 2012-0048218 discloses a color filter including a light changing portion containing a fluorescent substance.

However, such a method must separately produce a composition for forming a color filter layer and a color conversion layer, and therefore has the following problems: the manufacturing process becomes complicated, and the manufacturing time is prolonged.
