Abstract
A liquid crystal display device includes a plurality of pixel electrodes to which a data voltage is supplied, a plurality of common electrodes arranged to form electric fields with the pixel electrodes, a plurality of common wire lines commonly connected to the common electrodes in each horizontal line, a plurality of common voltage drive circuits to supply a common voltage to each of the corresponding common wire lines, and a controller for generating clock signals to control the common voltage drive circuits to invert an electric potential of the common voltage to be output from each of the common voltage drive circuits for each frame period.
