Abstract

Display unevenness in a display panel is suppressed. A display panel with a high aperture ratio of a pixel is provided. The display panel includes a first pixel electrode, a second pixel electrode, a third pixel electrode, a first light-emitting layer, a second light-emitting layer, a third light-emitting layer, a first common layer, a second common layer, a common electrode, and an auxiliary wiring. The first common layer is positioned over the first pixel electrode and the second pixel electrode. The first common layer has a portion overlapping with the first light-emitting layer and a portion overlapping with the second light-emitting layer. The second common layer is positioned over the third pixel electrode. The second common layer has a portion overlapping with the third light-emitting layer. The common electrode has a portion overlapping with the first pixel electrode with the first common layer and the first light-emitting layer provided therebetween, a portion overlapping with the second pixel electrode with the first common layer and the second light-emitting layer provided therebetween, a portion overlapping with the third pixel electrode with the second common layer and the third light-emitting layer provided therebetween, and a portion in contact with a top surface of the auxiliary wiring.
