A display apparatus allows size reduction without increasing manufacturing cost and can provide the greatest possible power saving effect by drive-method switching. The display apparatus has a moving-image/still-image determination circuit having an adder adding digital signals for one screen by receiving digital signals on a pixel basis of individual pixels constituting image signals for one screen, having a comparator comparing a result of addition of digital signals constituting image signals of an immediately-preceding screen and a result of addition of digital signals constituting image signals of the current screen, using a result of the comparison by the comparator 15 to determine the images to be moving images when the addition results are different from each other and to determine the images to be still images when the addition results are identical to each other, and outputting a determination signal according to the respective images.
