Video display apparatus capable of displaying different videos according to observing direction

摘要

A video display apparatus has one display screen capable of displaying a video corresponding to each of a plurality of observers. An illumination unit emits a first luminous flux and a second luminous flux in at least two different directions in a time divisional manner. A transmission-type display element displays respectively in a time divisional manner by means of raster scanning a first video whose light source is the first luminous flux and a second video whose light source is the second luminous flux. An illumination switching unit sequentially switches two luminous fluxes in synchronism with movement of a boundary portion between the first video and the second video in a display screen of the transmission-type display element.
