Abstract: To provide a display device capable of displaying a plurality of images by superimposition using a plurality of memory circuits provided in a pixel. A plurality of memory circuits are provided in a pixel, and signals corresponding to images for superimposition are retained in each of the plurality of memory circuits. In the pixel, the signals corresponding to the images for superimposition are added to each of the plurality of memory circuits. The signals are added to the signals retained in the memory circuits by capacitive coupling. A display element can display an image corresponding to a signal in which a signal written to a pixel through a wiring is added to the signals retained in the plurality of memory circuits. Reduction in the amount of arithmetic processing for displaying images by superimposition can be achieved.

Abstract: A display apparatus suitable for wide-grayscale display is provided. The display apparatus includes, in a pixel, two driving transistors and a light-emitting device that are connected in series. One of the transistors is a p-channel transistor and the other of the transistors is an n-channel transistor, and switching therebetween is performed for driving. Such a configuration can inhibit the change in a gate-source voltage in display with a high grayscale level. In addition, the use of a transistor containing a metal oxide in a channel formation region as the n-channel transistor enables an increase in display characteristics in display with a low grayscale level.
