LIQUID CRYSTAL DISPLAY DEVICE

摘要

In a liquid crystal display device, when the polarity of the source signal voltage does not change over horizontal scanning periods, an image writing pulse of a gate signal to be supplied to a gate bus line corresponding to a pixel in a j-th row rises before the source signal voltage changes to a value corresponding to the pixel in the j-th row. Then, the image writing pulse of the gate signal to be supplied to the gate bus line corresponding to the pixel in the j-th row falls. Thereafter, an image writing pulse of a gate signal to be supplied to a gate bus line corresponding to a pixel in a k-th row (j ? k) rises. After the image writing pulse of the gate signal to be supplied to the gate bus line corresponding to the pixel in the k-th row rises, the polarity of an auxiliary capacitance signal voltage to be applied to an auxiliary capacitance bus line corresponding to each of subpixels of the pixel in the j-th row is reversed.
