The present invention prevents a TFT liquid crystal display device from deteriorating its image quality due to the insufficiency of voltage written through TFTs. There is disclosed a display device that includes a display panel in which the plural 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 plural 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 plural 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 plural pixel electrodes, and corrects the video data to be written into the one of the plural pixel electrodes.
