Title:
METHOD FOR MANUFACTURING PIXEL-DEFINING LAYER
Document Type and Number:
WIPO Patent Application WO/2024/085389
Kind Code:
A1
Abstract:
The present invention is provided to increase reliability and a lifespan as a display having vivid colors and high resolution by implementing a colored pattern on an electrode substrate. The present invention provides a method for manufacturing a pixel-defining layer, which includes the steps of applying and coating a photosensitive composition, prebaking, exposure, development, and post-heat treatment, wherein after the post-heat treatment, a long axis of a green pixel has a length of 8.0-13.0㎛, a short axis thereof has a length of 6.0-9.0㎛, and a converted aperture ratio of the green pixel exceeds 32%. A pixel that forms a size within a range according to the present invention can allow implement of high-resolution black PDL, and manufacturing of a display having high brightness and a long lifespan depending on a driving voltage and current.
