Description

TECHNICAL FIELD [0001] The present invention relates to a binder resin, a colored photosensitive resin composition, a barrier structure including the same, and a display device including the binder resin, a colored photo resist composition,

The present invention relates to a binder resin, a colored photosensitive resin composition, a barrier structure including the same, and a display device including the same.

Display is becoming the most common means of information delivery in modern society. Therefore, a liquid crystal display (LCD) is one of widely used flat panel display devices, and a thin film transistor substrate having a pixel electrode and a color filter substrate having a common electrode formed thereon Facing each other and a liquid crystal layer interposed therebetween. In such a liquid crystal display device, a voltage is applied to the pixel electrode and the common electrode to rearrange the liquid crystal molecules in the liquid crystal layer, thereby displaying an image by adjusting the amount of light transmitted through the liquid crystal layer. The organic light emitting display (OLED) that is attracted attention as a next generation display is advantageous in the development of a flexible display because it uses a self-luminous element without using a liquid crystal as described above.

In the information society, as consumption pattern is diversified, low power consumption, light weight, thinness and high image quality can be realized, and it is necessary to maximize the space utilization and to carry the display easily. As a result, several new attempts have been made to make it more thinner. Therefore, the color filter layer of the liquid crystal display device is formed from the photosensitive composition using a photo process directly in the TFT structure. The pattern can be used as a color filter of a liquid crystal display device together with a colored pigment, as a transparent overcoat or as a spacer, and can be used as a barrier structure of an organic light emitting display.

In general LCD and OLED displays, efforts have been made to improve the brightness and contrast ratio. For example, QD quantum dot particles are used to improve the luminance or increase the color reproducibility, or to improve the contrast ratio by applying the colored barrier structure to the OLED And so on.

Korean Patent No. 10-1751646 has developed a binder resin having a compound structure aimed at high transparency and has conducted studies for improving the performance of an organic light emitting display through a colored photosensitive resin composition containing the binder resin. Typically, the visible light region is referred to as the visible light region visible from 380 nm to 780 nm. That is, the transmittance of the conventional resin shows the lowest transmittance at 380 nm, and the transmittance is also set at 80%, which is an invention for producing a transparent resin for use as a display material. Further, in the case of producing such a transparent resin, it is an object to produce a colored photosensitive resin composition using a colorant generally used.

On the other hand, the object of the present invention is to produce a resin having a low transmittance by introducing a high absorbance at a specific wavelength into a resin. The resin thus prepared is advantageous for forming a pattern having a color in the production of the colored photosensitive resin composition, with little or no constituent of the color material. Therefore, it is an object of the present invention to synthesize a new binder resin which the resin does not have.
