ABSTRACT:
Exemplary embodiments of the present invention reduce display irregularity in order to enhance display quality. A liquid crystal panel includes a plurality of pixel electrodes provided at intersections of a plurality of scanning lines and a plurality of data lines, a scanning line driving circuit to sequentially select the plurality of scanning lines, and a data line driving circuit to sample an image signal VID supplied to an image signal line that is provided in common to the plurality of data lines and to supply the sampled signal to each data line. A signal correcting circuit has a correction amount specifying circuit to specify a correction amount α of the image signal VID to be supplied to each data line based on the position of the data line with respect to the extending direction of the image signal line; and a correcting circuit to correct the image signal VID based on the correction amount α specified by the correction amount specifying circuit and to supply the corrected image signal VID to the image signal line.
