Abstract
A liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer sandwiched between the first and second substrates, a plurality of scanning lines arranged on the first substrate, a plurality of signal lines arranged on the first substrate, a plurality of first switches arranged at intersections of the scanning lines and the signal lines, a plurality of pixel electrodes each electrically connected to each of the first switches, a plurality of opposing electrodes each arranged in parallel with each of the pixel electrodes, and a signal line driver which switches a first voltage for driving a positive pole and a second voltage for driving a negative pole at a predetermined interval in accordance with a gradation, and outputs the positive or negative driving voltage to the signal lines, the signal line driver compensating for the first and second voltages such that averages of the first and second voltages in each of gradations are different from one another.
