Abstract
A liquid crystal display (LCD) apparatus time-divides a frame into a plurality of fields, in which lights having a color different from each other, are generated. The LCD apparatus includes a backlight unit. The backlight unit includes n of light-generating units sequentially generating the lights in the fields. An initial light-generating time of an nth light-generating unit being delayed by a predetermined time gap relative to the (n−1)th light-generating unit so that each of the fields includes a first period, in which one of the lights is generated, and a second period, in which at least two of the lights are generated. The light-generating units generate a peak light having a peak intensity in the first period. Thus, the intensity of light or the time period for which the light is generated, is controlled so that color mixing is minimized and color purity is improved.
