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.
