Abstract:
A method of manufacturing a display apparatus includes: forming a first lower lift-off layer, a first upper lift-off layer, and a first photoresist layer on a substrate on which a first pixel electrode is formed; forming a first masking layer including a first photoresist pattern, a first upper lift-off pattern, and a first lower lift-off pattern, which expose the first pixel electrode, by partially removing the first photoresist layer, the first upper lift-off layer, and the first lower lift-off layer; forming a first light emitting layer and a first counter electrode on the first pixel electrode by using the first masking layer; forming a first passivation layer on the first counter electrode; and removing the first masking layer.
