Abstract
A novel display device is provided. The display device includes a first layer including a driver circuit, a second layer including a plurality of pixel circuits, and a third layer including a plurality of light-emitting elements; the second layer is provided over the first layer; the third layer is provided over the second layer; and a conductive layer is provided between the driver circuit and the plurality of pixel circuits. The driver circuit has a function of controlling operations of the plurality of pixel circuits. One of the plurality of pixel circuits is electrically connected to one of the plurality of light-emitting elements. The pixel circuit has a function of controlling emission luminance of the light-emitting element.
