<p>Provided is a liquid crystal display apparatus capable of stopping the brightness control of a back light source on the featuring quantity of an input video signal, in case a multi-plane display was performed. The liquid crystal display apparatus comprises a liquid crystal panel (6) for displaying a picture, a light source for irradiating the liquid crystal panel (6), a backlight unit (7) for controlling the light source, a two-plane control unit (3), and a brightness control unit (4). In accordance with the featuring quantity of the input video signal, the brightness control unit (4) performs the control of the emitting brightness of the back light source, upon the backlight unit (7). In case it is decided by a notice from the two-plane control unit (3) that the display mode for displaying a plurality of planes was selected, the brightness control unit (4) controls the backlight unit (7), so that the emitting brightness of the back light source may be kept constant irrespective of the featuring quantity of the input video signal.</p> |
