Abstract
A display apparatus includes a substrate and a plurality of pixels disposed on the substrate. Each pixel includes a gate electrode disposed on the substrate, a gate dielectric layer disposed on the substrate and the gate electrode, an oxide semiconductor pattern disposed on the gate dielectric layer, a first insulating pattern disposed on the oxide semiconductor pattern that overlaps the gate electrode, a second insulating pattern disposed on the oxide semiconductor pattern and spaced apart from the first insulating pattern, source and drain electrodes spaced apart from each other on the oxide semiconductor pattern, a pixel electrode pattern disposed on the second insulating pattern to make contact with the source electrode, and a channel area defined where the oxide semiconductor pattern overlaps the gate electrode. A high carrier mobility channel is formed in the channel area when a turn-on voltage is applied to the gate electrode.
