Display device

A display device comprising:

• a first light-emitting device comprising a first lower electrode, a first light-emitting layer over the first lower electrode, 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 comprising a second lower electrode, a third light-emitting layer over the second lower electrode, 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 in the first light-emitting device and the second light-emitting device;
• and
• an auxiliary wiring electrically connected to the common electrode,
• wherein a color exhibited by a light-emitting material of the first light-emitting layer is different from a color exhibited by a light-emitting material of the second light-emitting layer,
• wherein a color exhibited by a light-emitting material of the third light-emitting layer is different from a color exhibited by a light-emitting material of the fourth light-emitting layer,
• wherein the auxiliary wiring comprises a first wiring layer and a second wiring layer,
• wherein the second wiring layer is electrically connected to the first wiring layer through a contact hole of an insulating layer,
• wherein the first wiring layer has a lattice shape in a top view, and
• wherein the first lower electrode, the second lower electrode, and the second wiring layer each comprise a region over the insulating layer.
