Title:
METHOD FOR MANUFACTURING PIXEL-DEFINING LAYER
Document Type and Number:
WIPO Patent Application WO/2024/085388
Kind Code:
A1
Abstract:
The present invention relates to a display with not only vivid colors but also high resolution by implementing a colored pattern on an electrode substrate, so as to improve reliability and lifespan. The present invention relates to a method for manufacturing a pixel-defining layer, comprising: a photosensitive composition application and coating step; a pre-bake step; an exposure step; a development step; and a post-heat treatment step, wherein, after the post-heat treatment step, the long-axis length of a red pixel is 15.8-19.8 μm and the short-axis length thereof is 11.0-15.0 μm, and the conversion opening ratio of the red pixel exceeds 25 %, and a pixel formed to a size within the ranges according to the present invention enables high-resolution implementation through a black PDL, and a display with high luminance and long lifespan may be produced according to a driving voltage and a current.
