ABSTRACT:
A liquid crystal display and its driving method are provided which enable a proper gamma correction to be made to each of red, green, and blue colors without causing a decrease in a number of gray levels in an output image and enable lowering in an image quality to be prevented. The liquid crystal display includes a liquid crystal panel in which pixel electrodes for each of the red, green, and blue colors are repeatedly arranged along a scanning line, a scanning line driving circuit to scan in every scanning period, an RGB (Red, Green, and Blue) switching reference gray-scale voltage producing circuit to produce a reference voltage corresponding to a voltage-transmittance characteristic of each color, and a signal line driving circuit to produce a signal voltage and to feed to each signal line.
