Display device and electronic device including the same

A display device comprising:

• a display module including a first non-folding region, a folding region, and a second non-folding region arranged in a first direction;
• a first support plate disposed on the display module;
• a second support plate disposed on the first support plate;
• a heat dissipation layer disposed between the first and second support plates;
• a first adhesive layer disposed between the first support plate and the heat dissipation layer, and defining an open portion overlapping the folding region;
• a second adhesive layer disposed between the second support plate and the heat dissipation layer, and defining an open portion overlapping the folding region;
• and
• a first step compensation layer overlapping the folding region, and disposed between the heat dissipation layer and the first support plate in a portion in which the first adhesive layer is open,
• wherein an opening defined in each of the first and second adhesive layers has a width greater than a width of the bending portion of the heat dissipation layer in the first direction and in a portion overlapping the folding region and
• the bending portion protrudes toward the second support plate so that the bending portion is closer to the second support plate than a surface of the second adhesive layer facing the second support plate is to the second support plate.

An electronic device comprising:

• a display device in which a first hole region through which an optical signal passes is defined;
• an electronic optical module which is disposed on the display device, overlaps the first hole region, and receives the optical signal;
• and
• a case for receiving the display device and the electronic optical module,
• wherein the display device includes:
• a display module including a first non-folding region, a folding region, and a second non-folding region arranged in a first direction;
• a first support plate disposed on the display module;
• a second support plate disposed on the first support plate;
• a heat dissipation layer disposed between the first and second support plates, and including a bending portion overlapping the folding region;
• a first adhesive layer disposed between the first support plate and the heat dissipation layer;
• and
• a second adhesive layer disposed between the second support plate and the heat dissipation layer,
• wherein an opening defined in each of the first and second adhesive layers has a width greater than a width of the bending portion of the heat dissipation layer in the first direction and in a portion overlapping the folding region, and
• the bending portion protrudes toward the second support plate so that the bending portion is closer to the second support plate than a surface of the second adhesive layer facing the second support plate is to the second support plate.
