Organic light emitting diode display

摘要

An organic light emitting display device comprises a common voltage line formed over a peripheral region of a substrate; a passivation layer formed over a pixel region of the substrate and the peripheral region; pixel electrodes formed over the pixel region; and a pixel defining layer formed over the pixel region and the peripheral region. The pixel defining layer defines pixel openings overlapping the pixel electrodes, respectively. The device further comprises organic light emitting layers formed over the pixel region, and disposed in the pixel openings and over the pixel electrodes, respectively; and a common electrode formed over the pixel and peripheral regions. The common electrode is disposed over the pixel defining layer and the organic light emitting layers. The common electrode contacts the common voltage line. The passivation layer comprises a portion overlapping the common voltage line but not overlapping the pixel defining layer.
