Method for preparing pixel defining layer

Abstract

The present disclosure is not only to ensure vivid colors but also to increase display reliability and lifespan by implementing a colored pattern with low outgas amount and moisture content on an electrode substrate; in other words, since it may cause a decrease in luminance and a decrease in lifespan due to pixel shrinkage if the amount of outgas in the panel after post-heat treatment is 15 ppm or more, or the moisture content is 50 ppm or more, the present disclosure is to minimize the generation of outgas and the moisture content in the panel state by maintaining sufficient heat and time and generating sufficient fume in the post-heat treatment step in order to minimize the outgas amount and moisture content after completing the post-heat treatment process by including a colorant according to the present disclosure.
