Patent ID: 11894384
Assignee: LG DISPLAY CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. 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; and
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,
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,
wherein the gate electrode has a stacked structure of a first hydrogen barrier layer and a low-resistance electrode layer,
wherein each of the first thin film transistor and the second thin film transistor includes a gate insulating layer between the oxide semiconductor pattern and the gate electrode, and
wherein the low-resistance electrode layer is disposed between the gate insulating layer and the first hydrogen barrier layer.
