Abstract
A liquid-crystal display apparatus is provided. The liquid-crystal display apparatus including: a light source for generating visible-domain light and invisible-domain light; a plurality of liquid-crystal devices laid out in a display face region of the liquid-crystal display apparatus for modulating visible-domain light and transmitting invisible domain light generated by the light source; a plurality of light receiving devices laid out in the display face region as devices each used for receiving invisible-domain light; a display driving section configured to drive the liquid-crystal devices so as to radiate visible-domain light from the display face as display light; a light-reception driving section configured to drive the light receiving devices to detect invisible-domain light radiated from the display face and reflected by a detection-subject object as detected light; and a detection section configured to detect the detection-subject object on the basis of a received-light signal obtained from the light receiving devices.
