Abstract

A display device includes: sub-pixels each including a memory block including memories; memory selection line groups each including memory selection lines electrically coupled to the memory blocks in the sub-pixels that belong to the corresponding row; a memory selection circuit configured to concurrently output memory selection signals to the memory selection line groups; a potential line; a conduction switch provided for at least one memory in the memory block on a one-to-one basis; and an operating-memory conduction circuit configured to output, to the conduction switch, an operation signal for determining whether to electrically couple or uncouple the potential line and the corresponding one memory. Each memory is capable of storing sub-pixel data therein when being coupled to the potential line. Each sub-pixel displays an image based on the sub-pixel data stored in one memory in the sub-pixel according to the memory selection line supplied with the memory selection signal.
