Classification: CPC H | IPC H

Claim 6:
7. The A display apparatus comprising:
a driving circuit on a device substrate, the driving circuit including a first thin film transistor and a second thin film transistor;
a first insulating layer on the first thin film transistor and the second thin film transistor of the driving circuit;
a second insulating layer on the first insulating layer;
a light-emitting device on the second insulating layer, the light-emitting device being electrically connected to the second thin film transistor of the driving circuit; and
a conductive pattern being electrically connected to a drain electrode of the second thin film transistor by penetrating the first insulating layer,
wherein the light-emitting device includes a first electrode being electrically connected to the conductive pattern by penetrating the second insulating layer,
wherein each of the first thin film transistor and the second thin film transistor includes an oxide semiconductor pattern and a gate electrode overlapping a portion of the oxide semiconductor pattern, and
wherein the gate electrode has a stacked structure of a first hydrogen barrier layer and a low-resistance electrode layer.
