Abstract
Provided is an implementation of a coloring pattern with a low moisture content on an electrode substrate to thereby improve display reliability and lifetime as well as vivid colors. That is, since when the moisture content is 50 ppm or more, it may cause a reduction in luminance and lifetime due to pixel shrinkage, in order to minimize the moisture content after completion of the post-baking process, the generation of moisture in the panel state is minimized by generating sufficient heat and time in the post-baking step, by including the colorant of the presently claimed subject matter.
