METHOD FOR MANUFACTURING PIXEL DEFINITION LAYER

WIPO Patent Application WO/2024/085390

A1

The purpose of the present invention is to improve the reliability and lifespan of a display having not only vivid colors but also high resolution by implementing a colored pattern on an electrode substrate. The present invention relates to a method for manufacturing a pixel definition layer, the method comprising steps for applying and coating, prebaking, exposing, developing, and post-heat treating a photosensitive composition, wherein after the post-heat treatment step, the long axis length of blue pixels is 20.5-25.5㎛, the short axis length of the blue pixels is 15.0-19.0㎛, and the converted aperture ratio of the blue pixels exceeds 43%. The pixels having a size within a range in accordance with the present invention make is possible to achieve the high resolution of black PDL and manufacture a display having a high brightness and long lifespan depending on driving voltage and current.
