A display device measures a user's blood pressure by detecting a photoplethysmography signal. A display device includes a display panel that includes a through hole and a pixel area that surrounds the through hole and includes pixels that display an image, a pressure sensor disposed on a surface of the display panel and configured to sense an externally applied pressure, a light-emitting member disposed at a position that overlaps the through hole of the display panel and outputs light toward a front side of the display panel through the through hole, and a light-receiving sensor that faces the front side of the display panel and is configured to sense light reflected from the front side of the display panel toward the display panel.
