Organic light-emitting display panel and method of fabricating the same
First Claim
1. An organic light-emitting display panel, comprising:
- a base substrate;
a first electrode layer including a plurality of first electrodes arranged on the base substrate;
a liquid-repelling pixel-defining layer including partition walls that define a plurality of pixels;
an organic light-emitting layer including a plurality of organic light-emitting patterns in the pixels, respectively; and
a second electrode layer on the organic light-emitting layer,wherein the organic light-emitting layer includes a plurality of primer patterns, the plurality of primer patterns;
being respectively disposed in the pixels,being separate from one another, andrespectively overlapping the first electrodes,wherein at least one of the primer patterns has an area different area from an area of the other primer patterns, andwherein the primer patterns have an affinity for liquid that is higher than an affinity for liquid of the liquid-pixel-defining layer.
