Abstract: An electronic device includes a display panel in which a display area and a non-display area are defined. The display panel includes a base layer in which a first non-folding area, a second non-folding area, and a folding area are defined, a plurality of pixels disposed on the base layer and disposed in the display area, a first protrusion disposed on the base layer and disposed in the non-display area, and a second protrusion that is disposed on the base layer and disposed in the non-display area and that surrounds the first protrusion. A first gap between the first and second protrusions that overlap the first non-folding area is greater than a second gap between the first and second protrusions that overlap the folding area.

Abstract: An electronic device includes a display panel including a folding area and a non-folding area which is adjacent to the folding area along a first direction, and a support member facing the display panel. The support member includes in order from the display panel, an upper plate which faces the folding area and the non-folding area, has a thickness and in which are defined a plurality of openings corresponding to the folding area, and a lower plate having a thickness which is greater than the thickness of the upper plate and including a first lower plate and a second lower plate each corresponding to the folding area and the non-folding area. At the folding area, the second lower plate is spaced apart from the first lower plate by a gap along the first direction.
