摘要： An object of the present disclosure is to implement a coloring pattern with a high optical density on an electrode substrate to improve display reliability and lifetime of a display as well as vivid colors. That is, the present disclosure relates to a composition and a method that can form the pattern of a pixel defining layer that can improve visibility and contrast by satisfying the optical density of 0.80/μm to 1.5/μm in the panel after post-baking treatment.

摘要： An object of the present disclosure is to implement a coloring pattem with a constant illuminance value on an electrode substrate to thereby increase display reliability and lifetime while reducing delamination of the hole transport layer (HTL) in the post-process. That is, when the roughness of the pattern after post-baking treatment is low, it may cause delamination of the hole transport layer (HTL) and a decrease in lifetime due to defective pixels, and thus a certain roughness can be obtained by minimizing the surface flow by leaving the substrate at a high temperature during post-baking treatment according to the present disclosure.
