Abstract
A liquid crystal display device of a field sequential driving mode is capable of improving flicker and obtaining a good contrast by driving at a certain driving frequency. The liquid crystal display device divides one frame into at least three sub-frames and displays R, G, B images for each sub-frame, and the one frame is driven at a driving frequency satisfying at least one of two conditions that flicker is less than 45% and that a contrast ratio is at least 100. The driving frequency driving the one frame ranges from 80 to 110 Hz. The driving frequency satisfying the condition that the flicker is less than 45% is more than 80 Hz. The driving frequency satisfying the condition that the contrast ratio is at least 100 is less than 110 Hz.
