ABSTRACT:
A top emission organic light emitting display with a reflective layer therein is provided. The reflective layer, a first electrode, an organic layer, and a transparent second electrode are subsequently formed on the substrate. When a bias voltage is applied to the first electrode and the transparent second electrode, the organic layer emits radiation. The reflective layer reflects radiation from the organic layer toward the transparent second electrode, and therefore the emission efficiency of the OLED increases.
