Abstract
At the time of partial drive, the levels of voltages applied to data lines SL1 to SLn are switched according to a rewrite frequency set for each region of a display screen. For example, in a still-image display region with a relatively low rewrite frequency, the levels of the voltages applied to the data lines SL1 to SLn are set to be higher than those for a moving-image display region with a relatively high rewrite frequency. By this, the same effect as that obtained when a counter voltage is switched according to the rewrite frequency can be obtained. Thus, flicker occurring in each region of the display screen can be suppressed.
