Abstract: According to one embodiment, a display device includes a first substrate, a second substrate, a liquid crystal layer and an illumination device. The first substrate includes a base, a sensor, a sensor circuit and a sensor light-shielding layer. The sensor is located between the base and the liquid crystal layer in a display area that includes pixels, and outputs a detection signal corresponding to light becoming incident from a side of the liquid crystal layer. The sensor circuit includes a switching element and is connected to the sensor. The sensor light-shielding layer is opposed to a channel area formed in a semiconductor layer included in the switching element, and blocks light from the illumination device on the channel area.
