Abstract: A display device includes a display panel, a support member supporting the display panel and including a perforated portion in which a plurality of openings are formed, and an adhesive layer disposed between the display panel and the support member, and at least partially filling the plurality of openings. Because adhesive material of the adhesive layer at least partially fills the plurality of openings, adhesion reliability between the support member and the buffer member is improved. For this reason, the adhesive layer may not peel off from the support member over time, and the reliability of the display device is improved.

Abstract: A display device includes a display panel and a cushion layer disposed below the display panel. The cushion layer includes a first foam layer having a first density, a second foam layer disposed above the first foam layer and having a second density less than the first density, and a third foam layer disposed above the second foam layer and having a third density greater than the first density. The third form layer is disposed closer to the display panel than the first foam layer. The display device provides improved surface quality, impact resistance, and restoration properties.
