Abstract: A display device includes a display panel including a front surface and a rear surface, a first circuit board electrically connected to a first side of the display panel, a second circuit board electrically connected to a second side opposite to the first side of the display panel, a third circuit board disposed on the rear surface and electrically connected to the first circuit board and the second circuit board, the third circuit board extending in a first direction, and a support plate disposed on the rear surface. The display panel is foldable along a folding line extending in a second direction. The support plate has a first opening extending along the folding line, and an opening pattern near a portion of the first opening. The third circuit board overlaps the portion of the first opening. The opening pattern includes slits and the third circuit board overlaps the slits.

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.
