Abstract

According to one embodiment, an optical sensor-equipped liquid crystal display device includes a display panel and a driver IC. The display panel includes a display area including pixels, a surrounding area surrounding the display area, peripheral circuits provided in the surrounding area, and an optical sensor outputting a detection signal in response to incident light. The peripheral circuit includes a shift register, and a gate switch group connected to the shift register and including a first gate switch and a second gate switch. The first gate switch is connected to a switching element for driving the pixel via a scanning line. The second gate switch is connected to a switching element included in a sensor circuit for driving the optical sensor via a scanning line for sensor.
