Abstract
A liquid crystal display device is formed by arranging a plurality of scanning lines, . . . to which scanning signals are successively applied and a plurality of signal lines, . . . to which data signals are successively applied to intersect at right angles. Mounted in the vicinity of each of the intersections of the scanning lines, . . . and signals lines, . . . are a TFTelectrically connected to both of the lines, and a pixel electrodeconnected to the TFTA common electrode is placed to face the pixel electrodewith liquid crystalstherebetween. One of electrodes of a pixel capacitance formed by the pixel electrodeis connected to a common linefor supplying a common signal to the common electrodeA dummy scanning linefor forming a capacitance is arranged outside of the scanning linelocated at the outermost position on a scanning start side of scanning signal. In this structure, since an equal parasitic capacitance is generated in the pixels irrespectively of their positions, it is possible to eliminate defects, such as deterioration of display quality due to an appearance of a bright line in particular pixels.
