ABSTRACT:
In a liquid crystal display device of the invention, a reference voltage having a maximum value higher than a maximum value of a signal voltage used for obtaining a predetermined liquid crystal application voltage-luminance characteristic and a minimum value lower than a minimum value of the signal voltage is formed, and a liquid crystal driving circuit forms a correction voltage to speed up a response of a liquid crystal element from this reference voltage, so that the speed of the response of the liquid crystal element is made high even at the time of change from a gray level to white or black.
