A display device, comprising:

• a display panel comprising a folding area and a non-folding area disposed adjacent to the folding area;
• a first support plate disposed on a lower portion of the display panel;
• a first functional layer disposed between the display panel and the first support plate;
• and
• a second functional layer disposed on a lower portion of the first support plate,
• wherein the non-folding area comprises:
• a first display area;
• and
• a second display area disposed adjacent to the first display area and having a higher light transmittance than the first display area,
• wherein each of the first display area and the second display area displays an image,
• wherein a first hole overlapping the second display area is displaying the image defined in the first support plate, a second hole overlapping the second display area is defined in the first functional layer, and a third hole overlapping the second display area is defined in the second functional layer, and
• in a plan view, a size of each of the first, second, and third holes is larger than a size of the second display area displaying the image, and the size of the first hole is different from the size of each of the second and third holes.

An electronic device, comprising:

• a display device in which a first transmissive area through which an optical signal passes is defined;
• an electro-optical device disposed below the display device, overlapping the first transmissive area, and configured to receive the optical signal;
• and
• a case configured to accommodate the display device and the electro-optical device,
• wherein the display device comprises:
• a display panel comprising a folding area and a non-folding area disposed adjacent to the folding area;
• and
• a first support plate disposed on a lower portion of the display panel,
• wherein the non-folding area comprises:
• a first display area;
• and
• a second display area disposed adjacent to the first display area and having a higher light transmittance than the first display area,
• wherein each of the first display area and the second display area displays an image,
• wherein a first hole overlapping the second display area displaying the image is defined in the first support plate in the non-folding area, and a size of the first hole is larger than a size of the second display area displaying the image in a plan view.
