PROBLEM TO BE SOLVED: To prevent an image different from an image intended to be displayed from being displayed. ! SOLUTION: A controller 20 stores image data of an image being displayed in a second storage section 31B and stores image data of an image to be newly displayed in a first storage section 31A. The controller 20 compares the image data stored in the first storage section 31A and the second storage section 31B and rewrites gradation for a pixel having the gradation to be changed in the case where the image being displayed corresponds to an image represented by the image data stored in the second storage section 31B. The controller 20 rewrites all pixels to white and subsequently rewrites the gradation on the basis of the image data stored in the first storage section 31A in the case where the image being displayed does not correspond to the image represented by the image data stored in the second storage section 31B. !
