Abstract: A display device includes a display panel including a main area, a bending area at which the display panel is bendable, and a sub area, in order. The main area includes a display area and a non-display area which is adjacent to the display area. The bending area connects the sub area to the main area at the non-display area thereof, and is recessed from outer side surfaces of the main area and the sub area, to define a recess portion of the display panel at the bending area.
