Disclosed is a display device comprising an optical sensor within a pixel region and a reduced number of bus lines for supplying drive signals to the optical sensor. The display device is provided with a display pixel circuit (8) and a sensor pixel circuit (9) in the pixel region (4) on an active matrix substrate. The sensor pixel circuit (9) comprises a light-receiving element (D1), a storage node that stores a charge corresponding to the amount of incident light that enters the light receiving element (D1), and a switching element (T2) for reading that reads the storage node charge. The display device also has: a drive circuit that supplies sensor drive signals that control the storage node reset and storage operations to the sensor pixel circuit (9), via source lines (SL) that supply display data signals to the display pixel circuit (8); and switching elements (M1, M2) for protection that are connected to a sensor control line (EL) that is provided other than in the source lines (SL) and which protect sensor signals in the sensor pixel circuit. |
