Abstract: According to one embodiment, a drive circuit for a display device includes a plurality of pixels. Each of the pixels includes a memory, and a display element driven based on output data of the memory. The drive circuit includes a storage control circuit for storing, in the memory, the data from a signal line, and a display control circuit which provides the display element with a display signal or a non-display signal based on the data stored in the memory. The drive circuit changes a display area from a first display state to a second display state. When the drive circuit sets the display area to the second display state, the drive circuit supplies a signal which does not depend on the image data to the display element.
