Abstract: A display device includes a first layer disposed on a base layer and including a first gate electrode, a first gate insulating layer, and an active layer, and a second layer disposed on the first layer and including a second gate electrode, a second gate insulating layer, and the active layer. The first layer and the second layer share the active layer. The first gate insulating layer has a first dielectric constant, and the second gate insulating layer has a second dielectric constant. The first dielectric constant and the second dielectric constant are different from each other.
