    Abstract: According to an aspect, a detection device includes: a first detection circuit including a first photodiode sensitive to first light and a second photodiode sensitive to second light; and a second detection circuit including a third photodiode sensitive to third light. The first photodiode and the second photodiode are coupled in series and in opposite directions to form a first detection element. One end side of the first detection element is coupled to a first signal line via a first transistor. Another end side of the first detection element is configured to be supplied with a first drive signal. A cathode of the third photodiode is coupled to a second signal line via a second transistor. An anode of the third photodiode is configured to be supplied with a second drive signal.

    Abstract: According to an aspect, a detection device includes: a base member having a first principal surface; a detection area provided to the first principal surface; a sensor including a plurality of photodiodes; gate lines; signal lines; and a light emission device. The light emission device includes light sources. A lit area in which the light emission device is lit up is a portion of the detection area overlapping the light sources. A portion of the detection area not overlapping the lit area is an unlit area in which the light emission device is not lit up. Photodiodes that overlap the unlit area are selected from among the photodiodes, and amounts of light received by the selected photodiodes are read.

    CPC classification number: H10K39/32

    Abstract: A detection device is a detection device including a plurality of optical sensors arranged on a substrate. In each of the optical sensors, a lower electrode, an electron transport layer, an active layer, a hole transport layer, and an upper electrode are stacked in a direction orthogonal to a surface of the substrate in the order as listed. The active layer contains an organic semiconductor. The hole transport layer includes a metal oxide layer and is provided on the active layer so as to be in contact therewith.
