PROBLEM TO BE SOLVED: To solve the problem that the total system is prevented from being miniaturized or being made at a low cost, when an external board or an external drive IC exists outside a panel. SOLUTION: In addition to a horizontal driver 16 and a vertical driver 17, peripheral driving circuits such as an interface circuit 13, a timing generator 14, a reference voltage driver 15, a CS driver 18, a VCOM (common voltage) driver 19, an electric potential setting circuit 20, and so forth are mounted on the same glass substrate 11 as a display part 12. When a display reset control pulse PCI is externally provided, a prescribed electric potential is written on a pixel, and, at the same time, the CS electric potential and the VCOM electric potential are set at the same electric potential as the pixel electric potential. By providing the same electric potential to the side of an opposite electrode, the white display is performed in the normally white type, and the black display is performed in the normally black type, thereby preventing the disturbance in image when a power source is turned on/off.
