Abstract: A display device may include a window module and a display module including a first non-folding region, a second non-folding region, and a folding region disposed between the first non-folding region and the second non-folding region. The display module may include a damping layer, a color filter layer, a display panel, and a lower member, which are sequentially stacked below the window module, and the damping layer may include polymer.

Abstract: A touch screen integrated display device includes a driving chip, a flexible printed circuit board, and a buffering member. The driving chip is disposed in a non-display area of a lower substrate. The flexible printed circuit board is connected to the lower substrate and covers at least a part of the driving chip. The buffering member disperses force applied to the lower substrate by the curved flexible printed circuit board. In the touch screen integrated display device, the tension which acts on the lower substrate by the curved touch printed circuit board is reduced or dispersed by the buffering member, so that minute deformation of the lower substrate may be reduced and the light leakage may be reduced.
