  • Patent number: 11943943
    Abstract: A detection device includes a substrate, a plurality of detection electrodes arranged in a detection area of the substrate, an organic semiconductor layer that covers the detection electrodes, and a counter electrode provided above the organic semiconductor layer. The organic semiconductor layer includes at least either of a first p-type semiconductor layer and a first n-type semiconductor layer, and an active layer. The active layer is provided in each overlapping area overlapping a corresponding one of the detection electrodes, and has a structure in which a p-type semiconductor area and an n-type semiconductor area are mixed and coexist. The first p-type semiconductor layer or the first n-type semiconductor layer is provided in a non-overlapping area not overlapping the detection electrode, and is provided between the adjacent active layers.
