Abstract: According to an aspect, a display device includes: an array substrate comprising reflective electrodes arrayed in a matrix having a row-column configuration in a first direction and a second direction and a light-transmitting conductive layer at least partially overlapping any one of the reflective electrodes when viewed in a third direction orthogonal to the first direction and the second direction; a counter substrate comprising a common electrode overlapping the reflective electrodes when viewed in the third direction and a color filter including a plurality of colors; and a backlight. The array substrate is disposed between the counter substrate and the backlight. Part of the light-transmitting conductive layer protrudes between two reflective electrodes adjacently disposed in the first direction among the reflective electrodes.

Abstract: According to one embodiment, a display device includes a display area where a plurality of pixels are arrayed, a first drive circuit arranged adjacent to the display area in a first direction, the first drive circuit configured to supply a drive signal to a gate electrode included in each of switching elements, and a memory power line extending in a second direction intersecting the first direction in the display area and configured to supply a potential to a memories. An outer edge of the display area is defined by outermost edges of the pixels located on an outermost side in the display area. A first distance from the first drive circuit to the outer edge is shorter than a second distance from the first drive circuit to the memory power line.

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.
