DISPLAY DEVICE

A display device includes a substrate, an active pattern disposed on the substrate, and including a first area, a second area, a (1-1)th channel area, a (1-2)th channel area, and a third area disposed between the (1-1)th channel area and the (1-2)th channel area, a first insulating layer disposed on the substrate and covering the active pattern, a second insulating layer which is disposed on the first insulating layer and in which an opening overlapping the (1-2)th channel area, the second area, and the third area is defined, a first gate electrode disposed on the first insulating layer and overlapping the (1-1)th channel area the (1-2)th channel area, respectively, and a high dielectric layer disposed on the first insulating layer and the second insulating layer, covering the first gate electrode, and filling the opening.
