Abstract
According to an aspect, a display device includes: sub-pixels arranged in row and column directions and each including a memory block including memories to store therein sub-pixel data; memory selection line groups corresponding to rows and each including memory selection lines electrically coupled to the memory blocks in the respective sub-pixels that belong to the corresponding row; and a memory selection circuit configured to concurrently output a memory selection signal to the memory selection line groups. 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.
