Classification: CPC H | IPC H

Claim 0:
1. A display apparatus comprising:
a substrate;
a first insulating layer on the substrate;
first metal layers on the first insulating layer and having a stress range between a compressive stress of about −700 megapascals (MPa) and a tensile stress of about 100 megapascals (MPa);
a second insulating layer on the first metal layers, the second insulating layer comprising:
a first layer covering the first metal layers; and
a second layer including a material different from a material of the first layer;

second metal layers between the substrate and the first insulating layer;
a first thin-film transistor on the substrate, the first thin-film transistor comprising:
a first semiconductor layer including an oxide semiconductor; and
a first gate electrode insulated from the first semiconductor layer; and

a storage capacitor comprising a first electrode and a second electrode insulated from the first electrode,
wherein the second metal layers are in a same layer as the first gate electrode.
