Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binder resin, a colored photosensitive resin composition, a display barrier rib structure including the same, and a self-luminous display device including the same. same}

The present invention relates to a binder resin, a colored photosensitive resin composition, a display bulkhead structure including the same, and a self-luminous display including the same.

Display is becoming the most common means of information delivery in modern society. Accordingly, many researches have been conducted on a display device, and a liquid crystal display (LCD) is one of widely used flat panel display devices. In a liquid crystal display device, a thin film transistor substrate on which a pixel electrode is formed and a color filter substrate on which a common electrode is formed are opposed to each other and a liquid crystal layer is 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. On the other hand, an organic light emitting display (OLED) that is attracted attention as a next generation display uses a self-luminous element instead of a liquid crystal unlike the above-mentioned general liquid crystal display (LCD), which is advantageous for the development of a flexible display.

In the display field, a barrier is a material used in a display for displaying resolution, and is used in a CDT (Color Display Tube), a CPT (Color Picture Tube), or a Plasma Display Panel (PDP) . However, due to recent developments of organic light emitting display (OLED) and quantum dot display, such barrier ribs can exhibit uniform performance in an advanced process, and various characteristics are required as needed, Which is more important than the bulkhead.

On the other hand, in the information society, as consumption pattern is diversified, low power consumption, light weight thinning, high image quality can be realized, and a display that maximizes space utilization and is portable is required. As a result, several new attempts have been made to make it more thinner. Typically, a pattern of a color filter layer of a liquid crystal display device is formed by photolithography. In this case, a material mainly used is a photoresist resin composition.

It is important that the photosensitive resin composition is resistant to the heat treatment, the chemical etching and the gas etching process applied to the photolithography process, and it is essential to secure the film hardness of the formed photosensitive resin composition and the high solubility in the developer do. In order to secure high heat resistance, high light resistance, and excellent solubility in a developing solution of such a photosensitive resin composition, among other things, the structure and properties of the binder resin should be considered in advance among components constituting the photosensitive resin composition. In this connection, Korean Patent Laid-Open No. 10-2017-0039561 discloses a cadobinder synthesis reaction and a binder resin having a novel structure, but has a problem that the film hardness is low and the solubility in a developer is low. This may cause a problem in the characteristics of the display product manufactured or used by using the binder product because it is a limitation on the use of the product and the uniform property is not expressed.

Accordingly, the development of a novel binder resin having excellent heat resistance of a colored resin composition in a display device, excellent light resistance in an exposure process, and molecular stability of a particle, This is a challenge to face.
