Abstract

A display device in which a voltage drop is inhibited adequately is provided. The display device includes a first light-emitting device including a first light-emitting layer, a first charge-generation layer over the first light-emitting layer, and a second light-emitting layer over the first charge-generation layer; a first color filter overlapping with the first light-emitting device; a second light-emitting device including a third light-emitting layer, a second charge-generation layer over the third light-emitting layer, and a fourth light-emitting layer over the second charge-generation layer; a second color filter overlapping with the second light-emitting device; a common electrode included in the first light-emitting device and the second light-emitting device; and an auxiliary wiring electrically connected to the common electrode. The auxiliary wiring includes a first wiring layer and a second wiring layer, the second wiring layer is electrically connected to the first wiring layer through a contact hole of an insulating layer, and the second wiring layer has a lattice shape in a top view.
