Display device

A display device comprising:

• a display panel including a first non-folding region, a folding region, and a second non-folding region, which are sequentially arranged along a first direction;
• a first plate disposed under the display panel;
• a heat dissipation layer disposed under the first plate;
• and
• a first adhesive layer disposed between the first plate and the heat dissipation layer,
• wherein the first adhesive layer includes a first sub adhesive layer overlapping the first non-folding region, and a second sub adhesive layer overlapping the second non-folding region,
• the first plate includes a plate-folding portion in which a plurality of openings overlapping the folding region are defined,
• the first sub adhesive layer and the second sub adhesive layer are spaced apart from each other by a first gap in the first direction, and
• a first width of the plate-folding portion in the first direction is smaller than a width of the first gap in the first direction by a distance in a range of about 0.5 mm to about 3 mm.
