Abstract
An object of the present disclosure is to implement a coloring pattern with a low amount of outgas on an electrode substrate to thereby increase reliability and lifetime of display as well as vivid colors of the same. That is, considering that 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, in order to minimize the amount of outgas after completion of the post-baking process, the generation of outgas in the panel state is minimized by generating sufficient fume in the post-baking step by way of including a colorant according to the present disclosure.
