Patent ID: 8710503

Claim:
An organic light-emitting display (OLED) device comprising: a substrate; a thin-film transistor (TFT) comprising: a gate electrode formed over the substrate; a gate insulation layer formed on the gate electrode; an active layer formed over the gate insulation layer and insulated from the gate electrode by the gate insulation layer; an insulation layer formed between the active layer and the source electrode, and further formed between the active layer and the drain electrode; source and drain electrodes insulated from the gate electrode and contacting the active layer; and wherein the insulation layer electrically insulates the active layer from the source and drain electrodes, and comprises a first insulation sub-layer contacting at least a portion of the active layer; and a second insulation sub-layer formed on the first insulation sub-layer and contacting the source and drain electrodes; and an organic light-emitting element formed over the TFT and electrically connected to the TFT.
