PCT No. PCT/JP95/00534 Sec. 371 Date Nov. 17, 1995 Sec. 102(e) Date Nov. 17, 1995 PCT Filed Mar. 23, 1995 PCT Pub. No. WO95/26109 PCT Pub. Date Sep. 28, 1995A method of driving a liquid crystal display device for converting a composite video signal into RGB analog video signals by a chrominance circuit, and controlling the transmittance of each pixel corresponding to each color or red, green and blue on a liquid crystal panel based on the voltage levels of the RGB analog video signals so as to perform color display. The method includes the steps of detecting a color saturation of a picture based on the composite video signal, and controlling the transmittance of a liquid crystal panel based on the transmittance characteristic (T-V curve a) of each pixel relative to normal RGB analog video signals in the case that the color saturation is less than a predetermined value. Based on the transmittance characteristic (T-V curve b) of each pixel relative to RGB analog video signals at the voltage levels where the transmittance of each pixel of the liquid crystal panel reaches the maximum value are set to be less than normal values, in the case that the color saturation is higher than the predetermined value. As a result, color saturation of a display of the liquid crystal panel is more enhanced than the actual color saturation of the RGB analog video signals in a picture portion having high color saturation, thereby improving color reproducibility.
