Abstract
The liquid crystal display device includes a liquid crystal panel including a common voltage correction unit that obtains predominant-polarity data based on polarities of image data to be supplied to pixel cells arranged in an nth one of pixel rows, obtains predominant-polarity data based on polarities of image data to be supplied to pixel cells arranged in an (n+1)th one of the pixel rows adjacent to the nth pixel row, obtains a sum of the two predominant-polarity data, and selects and outputting any one of a plurality of predetermined correction values based on the sum, and a common voltage output unit that corrects a common voltage based on the correction value from the common voltage correction unit and supplies the corrected common voltage to a common electrode.
