Abstract: A display device includes: an array substrate including reflective electrodes arrayed in a first direction and a second direction, light-transmitting conductive layers each overlapping at least part of one of the reflective electrodes when viewed in a third direction, and a signal line between two of the reflective electrodes adjacently disposed in the first direction and extending in the second direction; a counter substrate including 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. The color filter is configured such that different colors are arranged in the first direction and each color extends in the second direction. Part of one of the light-transmitting conductive layers protrudes between the two reflective electrodes and overlaps the signal line when viewed in the third direction.

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.
