Patent ID: RE40771

Claim:
A liquid crystal display device comprising: a pair of substrates sandwiching liquid crystals therebetween; a plurality of scanning lines to which scanning signals are successively applied; a plurality of signal lines to which data signals are successively applied, said signal lines intersecting said scanning lines at right angles; a switching element which is arranged in a vicinity of each of intersections of said scanning lines and said signal lines, and electrically connected to both of said scanning and signal lines; a pixel electrode connected to each of said switching elements; said scanning lines, signals lines, switching elements and pixel electrodes being formed on one of said substrates, a common electrode formed on the other of said substrates so that said common electrode faces said pixel electrode with said liquid crystals therebetween; a common line for supplying a common signal to said common electrode; a pixel capacitance, one of electrodes of said pixel capacitance formed by said pixel electrode being connected to said common line; and a dummy scanning line formed outside of one of said scanning lines located at an outermost position on either a scanning start side or a scanning end side of scanning signal, for producing a parasitic capacitance between said dummy scanning line and the pixel electrode connected to the scanning line located at the outermost position.
