Zusammenfassung:	Disclosed herein is a display device capable of recognizing a fine fingerprint without a complicated construction such as a bulky optical device. The display device comprises a display panel having a display area and a non-display area outside the display area; a light source disposed below the non-display area of the display panel to irradiate the display panel with light; a directional light unit disposed on an upper portion of the display panel, refracting the light supplied from the light source at a first angle to travel from the non-display area to the display area in total internal reflection, reflecting some of the totally internally reflected light at a second angle, and then supplying a light reflected by an object having biometric information to the display panel; and an optical sensor disposed below the display panel and receiving the light exited from the directional light unit.
