Fingerprint detection device and display device with fingerprint detection device

Abstract

A fingerprint detection device includes a substrate, a plurality of photoelectric conversion elements that are provided to the substrate and each output a signal corresponding to light emitted thereto, a plurality of signal lines coupled to the photoelectric conversion elements, a detection circuit that is electrically coupled to the photoelectric conversion elements through the signal lines, and a signal line selection circuit that switches the number of the signal lines to be coupled to the one detection circuit.
