Abstract
A display device with high resolution is provided. A display device with a high aperture ratio is provided. The display device includes a first pixel electrode, a second pixel electrode, a first insulating layer, a second insulating layer, a first EL layer, a second EL layer, and a common electrode. The first insulating layer covers end portions of the first pixel electrode and the second pixel electrode. The second insulating layer is provided over the first pixel electrode, the second pixel electrode, and the first insulating layer and covers an end portion of the first insulating layer. The first EL layer is provided over the first pixel electrode and the second EL layer is provided over the second pixel electrode. An end portion of the first EL layer and an end portion of the second EL layer face each other and overlap with the first insulating layer. The common electrode includes a portion overlapping with the first EL layer and a portion overlapping with the second EL layer. The first insulating layer includes an organic resin, and the second insulating layer includes an inorganic insulating material.
