The sensitivity of a photosensor is improved without decreasing read-out efficiency. The photosensor includes: a photodiode (D1) that converts received light into an electric current; a light shielding film (LS) that generates a parasitic capacitance between the photodiode (D1) and itself, a control signal line (RWST) that supplies a storage node (INT) with a reset signal and a read-out signal via the photodiode (D1); and a transistor (M2) connected with the storage node (INT) and an output line (OUT) for outputting, to the output line (OUT), an output signal corresponding to the potential of the storage node (INT) in response to the read-out signal. |
