    Abstract: A liquid crystal display apparatus includes a gamma mapping unit configured to receive red, green, and blue image information from an external device. During the first field, the gamma mapping unit generates first to third data signals for controlling the first to third pixels based on the red, green, and blue image information in synchronization with the backlight unit. During the second field, the gamma mapping unit generates fourth and fifth data signals for controlling the first and second pixels based on at least one of the first to third data signals or based on the red, green, and blue image information. As the quantity of the second color light leaked is adjusted through the first and second color filters in the second field, a color reproduction range and brightness of the liquid crystal display panel are improved. Thus, the display quality of the liquid crystal display apparatus is improved.
