| description | The present invention relates to a fingerprint recognition device, which can be made thinner and less expensive. A light-guide plate 2 guides light entering from an end face. A transmission liquid-crystal plate 1 is opened by pixel unit. Light from the protruding portions 31A and recessed portions 31B constituting the fingerprint of a finger 31 is collected via on aperture of transmission liquid-crystal plate 1, and converted from light energy to electrical energy by a photodetector element. The present invention is applicable to a fingerprint recognition device. |
