Abstract
An object of the present disclosure is to implement a coloring pattern with a high optical density on an electrode substrate to improve display reliability and lifetime as well as vivid colors as a display with high resolution. That is, the pixel having a size within the range according to the present disclosure can implement high resolution of a Black PDL and can manufacture a display with high luminance and long lifetime according to driving voltage and current.
Claims22
A method for preparing a pixel defining layer comprising applying and coating, pre-baking, exposing to light, developing, and post-baking of a photosensitive composition,
