Abstract
A display apparatus includes a substrate, a first insulating layer on the substrate, first metal layers on the first insulating layer and having a compressive stress or a tensile stress of about 100 megapascals (MPa) or less, and a second insulating layer including a first layer covering the first metal layers and a second layer including a material different from a material of the first layer.
Claims17
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.
