Abstract:
A display device, including: a display unit including a light emitting element that emits light, and a biometric information sensing unit disposed below the display unit, is provided, wherein the biometric information sensing unit receives light reflected by a biometric input, wherein the biometric information sensing unit includes: an optical system including a transmission part that passes the reflected light and an absorption part around the transmission part, wherein the absorption part absorbs the reflected light and pressure; a light detection sensor disposed below the transmission part of the optical system, wherein the light detection sensor receives the reflected light that passes through the transmission part; and a pressure detection sensor disposed below the absorption part of the optical system, wherein the pressure detection sensor detects the pressure that is transferred from the absorption part.
