Abstract
A novel display apparatus is provided. The display apparatus includes a first layer and a second layer over the first layer. The first layer includes a functional circuit. The second layer includes a display unit including a plurality of pixels and a memory unit including a plurality of memory cells. Each of the plurality of pixels includes a pixel circuit and a light-emitting element over the pixel circuit. The functional circuit includes a display unit driver circuit and a control circuit. The memory unit has a function of storing image data that is to be output through the display unit driver circuit to the display unit. The memory cell includes a first transistor for retaining a potential corresponding to the image data, and a second transistor for reading the potential. The first transistor is provided in the second layer, and the second transistor is provided in the first layer.
