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.
