In a display having a case where an image signal is inputted to the same row of a display section at an odd field period and an even field period, even if an AC driving is performed, a problem of a deterioration of a device due to a burning of a liquid crystal of an image display section by inputting the image signal including a still image such as a character or the like. Therefore, the polarity of the image signal is inverted every field and the polarity is further inverted every arbitrary n frames. In the n-frame inversion, a 1-field inversion pulse like φFRP that is outputted from a control circuit is further converted to an arbitrary n-frame inversion pulse by using an inverter, a switch, a counter, and the like. Thus, a signal processing circuit converts the image signals (R, G, B) to image signals like FIG. 1B whose polarities are inverted every one field and n fields.
