    Abstract: A photosensor includes: a first electrode; a second electrode; a photoelectric conversion layer that is located between the first and second electrodes and generates electric charges; a first charge blocking layer located between the first electrode and the photoelectric conversion layer; a second charge blocking layer located between the second electrode and the photoelectric conversion layer; a voltage supply circuit that applies a voltage to at least one of the first and second electrodes such that an electric field is generated in the photoelectric conversion layer; and a detection circuit that detects a signal corresponding to a change in capacitance between the first and second electrodes. The first charge blocking layer suppresses movement of electric charges between the photoelectric conversion layer and the first electrode. The second charge blocking layer suppresses movement of electric charges between the photoelectric conversion layer and the second electrode.

    Abstract: A photosensor includes a photoelectric converter including first and second electrodes and a photoelectric conversion layer therebetween; a transistor having a gate, a source and a drain; a connector electrically connecting the first electrode and the gate together; and one or more wiring layers including a part of the connector. The transistor outputs an electric signal from one of the source and the drain, the electric signal corresponding to a change in dielectric constant between the first electrode and the second electrode, the change being caused by incident light on the photoelectric conversion layer. The one or more wiring layers include a first line coupled to the one of the source and the drain and a second line supplied with a fixed voltage in a period during operation. A distance between the first line and the connector is less than a distance between the second line and the connector.
