PURPOSE: Liquid crystal display device is provided to realize a liquid crystal display device in which visibility at a time of display of moving pictures between gray levels is improved even in a case where a gray level change is slight. CONSTITUTION: In FIG. 1, reference numeral 9 designates a liquid crystal application voltage-luminance characteristic of each of liquid crystal elements constituting the liquid crystal display device. In the device, a reference voltage V8(P)/V9(N) corresponding to white is shifted to a low voltage side as indicated by V8'(P)/V9'(N). Besides, a reference voltage V0(P)/V17(N) corresponding to black is shifted to a high voltage side as indicated by V0'(P)/V17'(N). Incidentally, characters(P) and(N) mean(Positive) and(Negative), and express a positive reference voltage and a negative reference voltage, respectively. In the liquid crystal display device according to the first embodiment, while a liquid crystal application voltage(signal voltage) at which luminance corresponding to an inputted image signal is obtained is supplied to each of the liquid crystal elements by a liquid crystal driving circuit, the shifted reference voltage as shown in FIG. 1 is used, and the liquid crystal driving circuit supplies a correction voltage to each of the liquid crystal elements prior to the supply of the liquid crystal application voltage(signal voltage) at which luminance corresponding to the inputted image signal is obtained. By this, even at the time of change from a gray level to a gray level close to white or black, the liquid crystal application voltage becomes high unlike the prior art, and it becomes possible to speed up the liquid crystal response to luminance change toward the vicinity of white or black.
