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,
- wherein after the post-baking step, the length of the major axis of Blue pixel is 20.5 μm to 25.5 μm, the length of the minor axis of Blue pixel is 15.0 μm to 19.0 μm, and the converted aperture ratio of Blue pixel exceeds 43%.
