ABSTRACT:
An organic light-emitting display has a first pattern overlapping with one first electrode portion which overlaps with the via-hole. The first pattern is protruded upward as compared with the first electrode. The other first electrode portion on which the first pattern is not formed is exposed. An emission layer is located on the first electrode. A second pattern may be further formed around the first pattern. The second pattern is spaced apart from the first electrode and protruded upward as compared with the first electrode extended onto the via-hole insulating layer. The first pattern and the second pattern may be connected to each other. With this structure, deterioration of the organic emission layer can be prevented.
