ORGANIC LIGHT EMITTING DISPLAY AND MANUFACTURING METHOD FOR THE SAME

摘要

An organic light emitting diode (OLED) display comprises a substrate, a semiconductor layer portion disposed over the substrate and comprising an active region, a source region, and a drain region, a first insulation layer disposed over the substrate, a gate electrode disposed over the first insulation layer and overlapping the active region, and a second insulation layer disposed over the first insulation layer. First and second insulation material pieces are disposed over the second insulation layer. Source and drain electrodes are disposed over the first and second insulation material pieces and connected the source and drain regions through contact vias formed through the first and second insulation material pieces, respectively. A third insulation layer is disposed over the second insulation layer and covering the source electrode and the drain electrode. The display further includes a first electrode connected to the drain electrode, an organic light emission layer and a second electrode.
