Abstract
A transreflective liquid crystal display device includes an upper substrate () on which a color filter is disposed, a lower substrate () on which scanning lines and data lines are formed, a liquid crystal layer () sandwiched between the upper substrate () and the lower substrate () and a backlight unit () provided on the side of the lower substrate () opposite to the liquid crystal layer (). The lower substrate () and the upper substrate () are parallel, and the liquid crystal molecules of the liquid crystal layer () are arranged parallel the upper substrate () when no voltage is applied. A transparent electrode () is disposed on the side of the upper substrate () faced to the liquid crystal layer (), and there are comb-shaped electrodes () disposed on the side of the lower substrate () faced to the liquid crystal layer (). The comb-shaped electrodes () include a first comb-shaped electrode () and a second comb-shaped electrode () both of which are interdigitated. A method for driving the said display devices is also disclosed.
