Abstract
A thin film transistor substrate and an organic light-emitting diode (OLED) display are disclosed. In one aspect, the OLED includes a thin film transistor substrate. The thin film transistor substrate includes a substrate, a source electrode formed over the substrate, a drain electrode formed over the substrate and spaced apart from the source electrode, an oxide semiconductor layer, and a gate electrode. The oxide semiconductor layer includes a source area at least partially overlapping the source electrode, a drain area at least partially overlapping the drain electrode, and a channel area formed between the source area and the drain area. The gate electrode, which is insulated from the oxide semiconductor layer, has a first width at a first end thereof, a second width at a second end opposite to the first end thereof and the first width is different from the second width.
