Each sub-pixel displays an image based on the sub-pixel data stored in one of the memories in accordance with the memory selection line supplied with the memory selection signal. The number of times that the set value is changed is less than the number of times that images are switched from one to another based on the memory selection signal output from the memory selection circuit.

A display device includes an array of sub-pixels, each of which include a memory to store sub-pixel data. The display device also includes a plurality of memory selection line groups respectively corresponding to the sub-pixel memories in rows of the array. The memory selection line groups are operated under control of a memory selection circuit, which outputs a memory selection signal based on a set value, thereby to perform sequential switching of memory selection lines. The sequential switching of the memory selection lines results in a sequential switching of the image being displayed.
