Abstract:
A liquid-crystal display comprising:(a) a first plurality of pixel electrodes arranged in a matrix array having rows and columns;(b) a second plurality of pixel electrodes arranged along said rows and columns of said matrix array;(c) a first plurality of scanning lines arranged along said respective rows of said matrix array;(d) a second plurality of scanning lines arranged along said respective rows of said matrix arrays;(e) date lines arranged along said respective columns of said matrix array;(f) thin-film transistors arranged at respective intersections of said first and second pluralities of scanning lines with said data lines;(g) a first plurality of fixed-potential electrodes; and(h) a second plurality of fixed-potential electrodes;wherein each of said first plurality of pixel electrodes and a corresponding one of said second plurality of pixel electrodes are located at each side of a corresponding one of said data lines, forming an electrode pair;and wherein each of said first plurality of said scanning lines is used for supplying a first scanning signal to corresponding ones of said first plurality of pixel electrodes included in a corresponding one of said rows of said matrix array through corresponding ones of said TFTs during a first scanning subperiod of a predetermined scanning period;and wherein each of said second plurality of said scanning lines is used for supplying a second scanning signal to corresponding ones of said second plurality of pixel electrodes included in a corresponding one of said rows of said matrix array through corresponding ones of said transistors during a second scanning subperiod of said scanning period subsequent to said first scanning subperiod;and wherein each of said data lines is commonly used for supplying a data signal to corresponding ones of said electrode pairs included in a corresponding one of said columns of said matrix array through corresponding ones of said TFTs;and wherein each of said first plurality of fixed-potential electrodes is located between one of said first plurality of pixel electrodes and a corresponding one of said second pluralities of pixel electrodes that form one of said electrode pairs;and wherein each of said second plurality of fixed-potential electrodes is located between one of said first plurality of pixel electrodes and an adjoining one of said second plurality of pixel electrodes that are included in different ones of said electrode pairs;and wherein said first and second pluralities of fixed-potential electrodes are designed to be applied with a fixed electric potential on operation.
