Abstract: PROBLEM TO BE SOLVED: To efficiently supply a selection signal to multiplexed pixels. SOLUTION: Between time t0 and t2, firstly between time t0 and t1, a scanning lines Gn+1 and Gn+2 are selected and a pixel electrode A11 is driven, and following this, between the time t1 and t2, only Gn+1 is selected and a pixel electrode B11 is driven. Moreover, between the time t1 and t2, the scanning lines Gn+3 and Gn+4 are also selected and a pixel electrode A12 is driven. After the time t2, at least one of the scanning lines Gn+3 and Gn+4 is not selected until both of the scanning lines Gn+3 and Gn+4 are selected between time t4 and t5 and the pixel electrode A12 is driven. Thus, the pixel electrode A12 is preliminarily driven between the time t1 and t2, and is able to maintain a preliminarily applied potential until it is driven between the time t4 and t5.

Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display device with little image display failure or deterioration. SOLUTION: The device has a common wire 502, gate wire 503, source wire 204 and alignment film in the outer peripheral region of a liquid crystal cell. The alignment film is insulated by an insulating film from the gate wire 503 and the source wire 204. The common wire 502 has a common potential exposed part 401 through an opening formed in the insulating film and electrically connected with the alignment film. Since the common voltage which is near the average voltage of the cell is supplied on the alignment film, display failure in the screen or deterioration caused by impurity ions remaining on the surface of the alignment film or in the alignment film can be prevented.

Abstract: Disclosed is an image display device to secure uniformity of a screen without luminance unevenness by reducing the number of signal lines and enhancing accuracy in voltages to be applied to respective pixels. In an interval after a scan line Gn+2 is set to selection potential until the scan line Gn+2 is set to non-selection potential, a first display signal having first electric potential to be given to a pixel electrode A is supplied to a signal line, whereby the pixel electrode A and a pixel electrode B are provided with the first electric potential. In addition, after the scan line Gn+2 is set to the non-selection potential, a second display signal having second electric potential to be given to the pixel electrode B is supplied to the signal line, whereby the pixel electrode B is provided with the second electric potential. In this event, a variation of compensative potential for offsetting a difference between an electric potential variation corresponding to parasitic capacitance between the pixel electrode A and scan lines Gn+1 and Gn+2, and an electric potential variation corresponding to parasitic capacitance between the pixel electrode B and the scan line Gn+1, is given to the scan lines Gn+1 and Gn+2 for compensation.

Abstract: The number of signal lines is reduced, and the uniformity of the screen of a display with no luminance variation is ensured by enhancing the accuracy of the voltage applied to each pixel. (See Fig. 7) A first display signal havin g a first potential to be given to a pixel electrode (A) is supplied to a sign al line during the time t1 from the timing at which a scanning line (Gn+2) goes to a selection potential to the timing at which it goes to a nonselection potential to give the first potential to the pixel electrode (A) and a pixel electrode (B). A second display signal having a second potential to be given to the pixel electrode (B) is supplied to the signal line during the time t2 after the scanning line (Gn+2) goes to the nonselection potential. When the second potential is given to the pixel electrode (B), a compensation potenti al variation for canceling the difference between the potential variation corresponding to the parasitic capacitance between the pixel electrode (A) a nd the scanning lines (Gn+1, Gn+2) and the potential variation corresponding to the parasitic capacitance between the pixel electrode (B) and the scanning line (Gn+1) is given to the scanning line (Gn+1) to effect compensation.
