摘要:
The present invention provides a liquid crystal display device which hardly causes image sticking in a panel in which Cgd gradation is performed, even when the pixel capacitances of the picture elements are different from one another. The liquid crystal display device of the present invention is a liquid crystal display device which includes a pair of substrates and a liquid crystal layer sandwiched between the pair of substrates, and is configured such that a pixel is formed by picture elements of a plurality of colors, wherein one of the pair of substrates includes scanning lines, signal lines, storage capacitor lines, thin film transistors connected to both of the scanning lines and the signal lines, and pixel electrodes connected to the thin film transistors; the other of the pair of substrates includes a counter electrode; the pixel electrodes are arranged for the picture elements; a scanning line and a pixel electrode form a gate-drain capacitance; the gate-drain capacitance formed by a pixel electrode with a larger pixel capacitance among the pixel electrodes arranged in one pixel is larger than the gate-drain capacitance formed by a pixel electrode with a smaller pixel capacitance among the pixel electrodes arranged in the one pixel; an overlapping area of each of the pixel electrodes overlapped with the scanning line initially increases in a travelling direction of a scanning line signal but a rate of the increase subsequently decreases, in each of the pixel electrodes respectively arranged for the picture elements of single colors; and rates of increase are different among the pixel electrodes with different pixel capacitances.
