DISPLAY DEVICE
First Claim
1. A display device comprising an active matrix substrate including a plurality of gate lines, a plurality of source lines, and display switching elements arranged in correspondence with respective points of intersection of the plurality of gate lines and the plurality of source lines, the display device further comprising:
- optical sensors provided in a pixel region of the active matrix substrate; and
a plurality of sensor row lines arranged in correspondence with the optical sensors,wherein supply of a voltage to the optical sensors and reading of a luminance signal from the optical sensors are performed through the plurality of source lines by a common column driver circuit that drives the display switching elements.

Abstract
The present invention provides a display device with an image capture function including optical sensors in its pixels, in particular, a display device which allows a reduction in the size of a substrate and in power consumption by reducing the area of a peripheral region not contributory to displaying. The display device includes: an active matrix substrate (100) including a plurality of gate lines (7), a plurality of source lines (9), and display switching elements arranged in correspondence with respective points of intersection of the plurality of gate lines and the plurality of source lines. The display device further includes: optical sensors (10) provided in a pixel region (1) of the active matrix substrate (100); and a plurality of sensor row lines (8) arranged in correspondence with the optical sensors (10). Supply of a voltage to the optical sensors (10) and reading of a luminance signal from the optical sensors are performed through the plurality of source lines (9) by a common column driver circuit that drives the display switching elements.
