Abstract
A display device includes a drive circuit to which video data is supplied from the outside; video lines to which video signals outputted from the drive circuit are supplied; and pixels to which the video signals are supplied through the video lines. The drive circuit includes a static random access memory which stores the video data in memory cells. The drive circuit is configured to perform writing only on selected memory cells that are connected to shared writing and reading word lines, to drive other memory cells connected to the shared writing and reading word lines and not selected to perform writing to output video data respectively stored therein to a reading data line, and then to rewrite the video data back to the non-selected memory cells, without precharging the memory cells that are connected to shared writing and reading word lines.
