Patent ID: 6989808

Claim:
A method of driving a liquid crystal display device, said liquid crystal display device comprising: a first substrate; a second substrate opposing said first substrate with a gap therebetween; a liquid crystal layer confined in said gap; a thin-film transistor formed on said first substrate; a data bus line formed on said first substrate in electrical connection with said thin-film transistor, said data bus line supplying an alternate-current driving voltage signal to said thin-film transistor; a pixel electrode provided on said first substrate in electrical connection to said thin-film transistor; an auxiliary electrode having an H-shaped form including a pair of parallel conductor portions and a conductor portion connecting said parallel conductor portions, formed on said first substrate in the vicinity of said data bus line such that said parallel conductor portions extend along said data bus line and so as to form an auxiliary capacitance connected parallel to said pixel electrode, said auxiliary electrode being disposed so as to induce a lateral electric field between said auxiliary electrode and said data bus line; and an opposing electrode formed on said second substrate, said method comprising the step of: applying to said auxiliary electrode a common voltage substantially equal to a central voltage of said alternate-current driving voltage signal, wherein the liquid crystal display device is a twisted-nematic type.
