Abstract
Disclosed is a display device which includes a display module including a non-folding area and a folding area arranged in a first direction and a support plate including a folding part that overlaps the folding area. An opening extending in a second direction crossing the first direction is defined in the folding part, and the opening includes a first opening defined in a lower surface of the folding part and a second opening defined above the first opening. In the second direction, a first length of the first opening and a second length of the second opening are different from each other.
