Abstract
The present invention relates to a liquid crystal display of a time divisional color display, which includes a plurality of pixels having liquid crystal capacitors, respectively, and light is not supplied to some pixels and light supplied to other pixels. Preferably, data voltages are applied to the pixels to which light is not supplied and data voltages are not applied to the pixel to which light is supplied. Accordingly, since a liquid crystal panel assembly is divided into several areas to be scanned sequentially and a light source of a light source unit corresponding to the area being scanned is maintained in light-off state, it is possible to secure enough data scan time as well as to increase light-on-time of the light sources. With this, time to charge electric charges of the liquid crystal capacitors is increased to improve image quality, and, according as light-on time of the light sources is increased, clearness of the image quality is also increased.
