    Abstract: Disclosed herein are a display device and a mobile terminal device including the same, which include a display panel including a screen in which a plurality of display pixels which are sequentially scanned, and a plurality of sensor pixels which are exposed to a light during an exposure time to convert the light into an electric current are disposed. While the display pixels disposed in the first area of the screen are scanned, the sensor pixels are exposed. While the display pixels in the second area of the screen are scanned, sensor data is output from the sensor pixels and then the sensor pixels are initialized.
