Abstract: Provided is a display device. The display device includes: a substrate; a gate line disposed on the substrate; a transistor including a part of the gate line; and a light-emitting element connected to the transistor, in which the gate line includes a first layer including aluminum or an aluminum alloy, a second layer including titanium nitride, and a third layer including metallic titanium nitride. An N/Ti molar ratio of the metallic titanium nitride may be in a range from about 0.2 to about 0.75.

Abstract: A transistor is positioned on a substrate. The transistor includes a semiconductor layer. A buffer layer is positioned between the substrate and the semiconductor layer of the transistor, including an insulating material. A bottom layer is positioned between the substrate and the buffer layer. The bottom layer and the semiconductor layer overlap each other. The bottom layer includes a first layer, a second layer, and a third layer that are stacked on each other in a direction away from the substrate.
