Abstract: A method of manufacturing an organic light emitting display includes: patterning an amorphous silicon layer to form an amorphous silicon layer pattern; forming an insulating layer on the amorphous silicon layer pattern; forming a gate electrode on a part of the insulating layer which corresponds to the amorphous silicon layer pattern; forming a blocking film on the gate electrode and the insulating layer; doping an impurity in a part of the amorphous silicon layer pattern; annealing the amorphous silicon layer pattern on which the impurity is doped to form a semiconductor layer; removing the blocking film; etching the insulating layer using the gate electrode as a mask to form a gate insulating layer below the gate electrode; forming an interlayer insulating layer using an organic insulator on a buffer layer, the gate electrode, and the semiconductor layer.

Abstract: A display device includes a substrate, a display element layer disposed on a first surface of the substrate and including a light emitting element that emits light, and a pixel circuit layer disposed on the display element layer and including a transistor electrically connected to the light emitting element. The display element layer includes a first contact electrode electrically connected to a first end of the light emitting element, and a second contact electrode electrically connected to a second end of the light emitting element. The pixel circuit layer includes a reflective layer disposed on the display element layer and overlapping the light emitting element. One of the first contact electrode and the second contact electrode is electrically connected to the transistor. The reflective layer reflects the light emitted from the light emitting element toward a second surface of the substrate.
