Abstract
A display device includes a first conductive layer; a first insulating layer on the first conductive layer; a semiconductor layer disposed on the first insulating layer and electrically connected to the first conductive layer; a second conductive layer disposed on the semiconductor layer and electrically connected to the first conductive layer; and light emitting elements on the second conductive layer. A thickness of a part of the first insulating layer in a first area, which overlaps the semiconductor layer in a plan view, is different from a thickness of another part of the first insulating layer in a second area, which is exposed by the semiconductor layer.
