Abstract
A display device with a narrow bezel is provided. The display device includes a pixel circuit and a driver circuit which are provided on the same plane. The driver circuit includes a selection circuit and a buffer circuit. The selection circuit includes a first transistor. The buffer circuit includes a second transistor. The first transistor has a region overlapping with the second transistor. One of a source and a drain of the first transistor is electrically connected to a gate of the second transistor. One of a source and a drain of the second transistor is electrically connected to the pixel circuit.
