ORGANIC LIGHT EMITTING DISPLAY

摘要

An organic light emitting display (OLED) including a thin film transistor (TFT) including a gate electrode, an active layer, and source and drain electrodes, the active layer being insulated from the gate electrode and including an oxide semiconductor and the source and drain electrodes being insulated from the gate electrode and contacting the active layer; a first insulation layer covering the TFT; a second insulation layer on the first insulation layer, the second insulation layer being formed of amorphous silicon without doping; a pixel electrode on the second insulation layer; a third insulation layer on the second insulation layer, the third insulation layer covering an edge of the pixel electrode; an organic light emitting layer on the pixel electrode; and a facing electrode on the organic light emitting layer and the third insulation layer.
