Abstract
Provided is a display device having a first pixel and a second pixel adjacent to the first pixel. The first pixel includes a first pixel electrode, a first EL layer over the first pixel electrode, and a second electrode over the first EL layer. The second pixel includes a second pixel electrode, a second EL layer over the second pixel electrode, and the second electrode over the second EL layer. The display device further possesses a first cap layer over the second electrode, a second cap layer over the first cap layer and overlapping with the first EL layer, and a third cap layer covering the second cap layer, overlapping with the first EL layer and the second EL layer, and in contact with the first cap layer in a region overlapping with the second EL layer.
