Abstract: A detection device includes: a substrate having a sensor region in which photosensors are arranged in a first direction and a second direction. In the sensor region, the substrate includes: read control scan lines extending in the first direction and configured to transmit read control signals; and output signal lines extending in the second direction. The photosensors includes: dummy elements comprising first photodiodes and arranged along a contour of the sensor region; and detection elements comprising second photodiodes and arranged on an inner side of a dummy region in which the dummy elements are arranged. The dummy elements are coupled to neither the read control scan lines nor the output signal lines. The detection elements are coupled to the read control scan lines and the output signal lines and are configured to, after receiving the read control signals, output signals generated by the first photodiodes to the output signal lines.

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.
