A liquid crystal display apparatus includes a backlight configured to emit red light, green light, and blue light for forming an image, a liquid crystal panel including a plurality of pixels through which light components supplied by the backlight respectively pass, configured to control transmittances of the plurality of pixels to form an image, and a backlight controller configured to control respective intensities of the red light, the green light, and the blue light emitted by the backlight. The backlight controller is configured to compensate for a black color coordinate value generated with respect to a predetermined color by controlling the backlight such that a second red light intensity and a second green light intensity are larger than a first red light intensity and a first green light intensity and a second blue light intensity are smaller than a first blue light intensity. A black color coordinate value may be made correspond to a white color coordinate value.
