Patent ID: 8188956

Claim:
A display device comprising: a plurality of scanning signal lines; a plurality of video signal lines; a plurality of TFTs; a plurality of pixel electrodes connected to sources of the TFTs; a display panel in which the plurality of pixel electrodes are positioned between two neighboring video signal lines and arranged in the extending direction of the video signal lines, a pixel electrode connected to one of the two neighboring video signal lines through a TFT and a pixel electrode connected to the other video signal line through a TFT being alternately arranged; and a correction circuit that compares the tone of video data to be written into one of the plurality of pixel electrodes against the tone of video data to be written into a preceding pixel electrode that is connected through a TFT to the video signal line, to which the one of the plurality of pixel electrodes is also connected through a TFT, and placed one position toward a signal input end of the video signal line as compared to the one of the plurality of pixel electrodes, and corrects the video data to be written into the one of the plurality of pixel electrodes; wherein the correction circuit includes tone correction means which makes a correction by changing the tone of video data to be written into the one of the plurality of pixel electrodes; and wherein, when the distance between the one of the plurality of pixel electrodes and the signal input end of the video signal line is greater than a predetermined value, the tone correction means corrects the tone of the video data.
