Abstract:
According to an aspect, a display device includes a plurality of sub-pixels. Each of the sub-pixels includes a memory block including a memory configured to store therein sub-pixel data and a sub-pixel electrode coupled to the memory block. The memory includes first and second transistors configured to store therein the sub-pixel data in accordance with an electrical charge of a floating gate, the first and second transistors include respective drains that are coupled to each other, and a coupling point of the drains is coupled to a node. The sub-pixel electrode is coupled to the node, and each of the sub-pixels is configured to display an image based on a potential of the node.
