Abstract:
1. A liquid crystal display apparatus comprising: a liquid crystal display unit including a pair of substrates, at least one of which is transparent, a liquid crystal layer sandwiched by said pair of substrates, a plurality of electrodes for applying an electric field to at least one of said pair of substrates, and a plurality of active elements connected to said plurality of electrodes; a lighting device including a plurality of light sources which is divided into plural regions for illuminating corresponding plural illumination regions of an entirety of a display area of the liquid crystal display unit; and a control unit for controlling ON and OFF states of a light source for each of the plural regions into which said lighting device is divided, in synchronization with horizontal synchronization signals and vertical synchronization signals, so that the ON state of individual ones of the plural regions of the divided lighting device is shifted among the plural regions, and an individual illumination region of the plural illumination regions of the entirety of the display area of the liquid crystal display unit is correspondingly shifted therewith.
