Abstract: A display device is provided. The display device includes a base; a gate conductor disposed directly on the base and including a gate line and a gate electrode; a gate insulating layer disposed on the gate conductor and including an overlap portion, which overlaps with the gate conductor, and a non-overlap portion, which is connected to the overlap portion, does not overlap with the gate conductor, and is spaced apart from the base; and a semiconductor pattern disposed on the gate insulating layer and overlapping with the gate electrode, wherein edges of the gate insulating layer project further than edges of the gate conductor and edges of the semiconductor pattern.
