ABSTRACT:
In an organic electro-luminescent display, a pixel circuit is disposed in a unit pixel region defined on a substrate. A passivation layer covers the entire unit pixel region including the pixel circuit. An organic light emitting diode (“OLED”) including a transparent lower electrode formed on a portion of the passivation layer which does not overlap the pixel circuit, an OLED layer, and an upper electrode are sequentially formed on the passivation layer. The transparent lower electrode is a transparent anode of the OLED. A protective layer is formed of the same material as the transparent lower electrode and disposed on a portion of the passivation layer corresponding to the pixel circuit to cover and protect the pixel circuit.
