Abstract: An object of the present disclosure is to implement 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 present disclosure.

Abstract: An object of the present disclosure is to improve display reliability and lifetime as well as vivid colors. When there remain residues in the washing part due to incomplete removal during the developing step, it can cause dark spots or pixel off due to the residues, and thus residue-free pixels can be formed by optimizing the temperature and time for developing. Additionally, when the amount of outgas in the panel after post-baking is 15 ppm or more, it may cause a reduction in luminance and lifetime due to pixel shrinkage. Therefore, in order to minimize the amount of outgas after completion of the post-baking process, the generation of outgas in the panel state can be minimized by generating sufficient fume in the post-baking step, in addition to forming clean pixels in the developing step.
