Abstract
A display device includes an optical fingerprint sensor; a display panel; a patterned film disposed below the display panel and having an opening portion that exposes the optical fingerprint sensor; a heat dissipating layer disposed below the patterned film, and that dissipates heat; and a cushion layer disposed between the patterned film and the heat dissipating layer, and that absorbs an impact. The optical fingerprint sensor is disposed below the cushion layer, and the heat dissipating layer has an opening portion that has a size larger than a size of the opening portion of the patterned film.
