Method for preparing pixel define layer

Abstract

Provided is a method for ensuring vivid colors and increasing display reliability and lifespan by implementing a colored pattern with high optical density on an electrode substrate, where the method uses a pigment dispersion in which a pigment having a size of 100 nm or less is used in order to increase the optical density and reduce roughness after completing the post-heat treatment process by including a colorant according to the present disclosure, and the method can minimize the reduction in the lifespan due to moisture in the panel state by minimizing the moisture content after completing the post-heat treatment process.

Dependencies are inferred from the claim text.
