Abstract
A display apparatus includes a signal driving circuit and a display control circuit. When a refresh rate is changed from a first frequency to a second frequency higher than the first frequency, the display control circuit sets a third time period between a first time period having the refresh rate at the first frequency and a second time period having the refresh rate at the second frequency. The display control circuit rewrites for the third time period an image to be displayed on a display panel by alternating the polarity of a pixel voltage between a positive polarity and a negative polarity at a third frequency higher than the second frequency.
