<p>Disclosed is a display device having an optical sensor with increased sensitivity. The display device is provided with: a display panel, which includes a plurality of display pixel circuits (8) and a plurality of sensor pixel circuits (9a) in a display region (4); and a drive circuit (7) which supplies a drive signal to the sensor pixel circuits (9a). The sensor pixel circuits (9a) are provided with: a light receiving element (PD1); a storage node (INT), which retains electrical charge corresponding to the light amount which has entered into the light receiving element (PD1); and a read-out switching element (M1), which is connected to the storage node (INT). The display device is further provided with a first switching element (T1), which is connected between the light receiving element (PD1) and the storage node (INT), and which operates in a saturation region, and a second switching element (T2) which resets the storage node (INT).</p> |
