Patent ID: 8614443

Claim:
A display apparatus comprising: a substrate; and a plurality of pixels disposed on the substrate, each pixel comprising: a gate electrode disposed on the substrate; a gate dielectric layer disposed on the substrate and the gate electrode; an oxide semiconductor pattern that overlaps the gate electrode disposed on the gate dielectric layer; a first insulating pattern disposed directly, on the oxide semiconductor pattern that overlaps the gate electrode; a second insulating pattern disposed directly on the oxide semiconductor pattern and spaced apart from the first insulating pattern; a drain electrode disposed on the oxide semiconductor pattern; a source electrode disposed on the oxide semiconductor pattern and spaced apart from the drain electrode; and a pixel electrode pattern disposed on the second insulating pattern that contacts the drain electrode, wherein the drain electrode covers a portion of the pixel electrode pattern and the oxide semiconductor pattern between the first and second insulating patterns, the second insulating pattern is spaced apart from the gate electrode, and a sidewall of the second insulating pattern is aligned and coplanar with a sidewall of the pixel electrode pattern.
