Abstract
A wave A is used as a signal inputted to a liquid crystal panel via an operational amplifier OP. The wave A is a superimposed wave made up of, for example, a first rectangular wave to be the base of a driving signal and a second wave capable of increasing respective amplitudes of the first wave in rising and falling directions. Because a wave A is superimposed, using the wave A as the driving signal of the liquid crystal panel surely results in increase in a quantity of charges with which respective pixels of the liquid crystal panel are supplied at early stages of writing, more than simply applying the wave A to the liquid crystal panel. Consequently, even when a charge supplying ability of a reference voltage line is considerably low, a desired charging quantity can surely be obtained in respective pixels within desired writing time, thereby preventing crosstalk having different degrees depending on a location even when a charge supplying ability for the respective pixels of the liquid crystal panel is considerably low.
