Patent ID: 7161574

Claim:
A liquid crystal display device comprising: a liquid crystal display element having a plurality of pixels constituting a screen; a gate driving means for dividing a frame period into a plurality of write periods and outputting gate signals to select the pixels sequentially during the write periods; and a source driving means for forming each of source signals such that the source signal includes a picture signal and a non-picture signal respectively assigned for the write periods and writing each of the source signals corresponding to each of the selected pixels to each of the pixels with the polarity of the picture signal and non-picture signal being alternated, the liquid crystal display device displaying an image responsive to the source signals on the screen of the liquid crystal display element in such a manner that a transmittivity of liquid crystal of each of the pixels is controlled in accordance with the written source signal, wherein the source driving means writes the non-picture signal and the picture signal to each of the pixels in such a manner that the non-picture signal to be written to a pixel and the picture signal to be written subsequently to the pixel have an identical polarity.
