ABSTRACT:
A liquid crystal display device, in which the liquid crystal molecules are aligned vertically when no voltage is applied, includes pixels each having plural sub-pixel electrodes, a data bus drive circuit for applying drive signals to the sub-pixel electrodes via a data bus line and a switching element, and alignment regulation structure for regulating the direction of alignment of liquid crystal molecules. The first and second sub-pixel electrodes have different areas. The data bus drive circuit applies a first drive signal, which causes luminance to change from minimum to maximum for an increase of input grayscale of image signal, to the first sub-pixel electrode, and a second drive signal, which causes the luminance to be lower than the first drive signal, to the second sub-pixel electrode.
