Abstract: A display device includes a substrate including a first recess portion, a semiconductor layer that overlaps the first recess portion, the semiconductor layer including protrusions and depressions conforming to a shape of the first recess portion, and a gate electrode that overlaps the first recess portion and the semiconductor layer, the gate electrode including protrusions and depressions conforming to the shape of the first recess portion. A thickness of the substrate in the first recess portion is less than a thickness of the substrate in a non-recess portion, excluding the first recess portion.
