A liquid-crystal display, having a plurality of pixel areas and a plurality of photodetection areas for detecting light disposed in a two-dimensional manner, includes first switching elements each provided for the corresponding pixel area and switching the drive of the corresponding pixel area, and second switching elements formed on the same layer as the first switching elements and each switching a photosensor element provided for the corresponding photodetection area. First sensor electrodes connected to the photosensor elements are formed on the same layer as switching electrodes connected to the second switching elements.
