Abstract

To provide a method of manufacturing a display device capable of high resolution. A first EL layer, a first layer, and a second layer are formed over a first pixel electrode; a second EL layer, a third layer, and a fourth layer are formed over the second pixel electrode; a resin layer covering an end portion of the second layer and an end portion of the fourth layer is formed by applying a photosensitive resin, exposing the photosensitive resin to light, and developing the photosensitive resin; a top surface of the first EL layer and a top surface of the second EL layer are exposed by etching parts of the first layer, the second layer, the third layer, and the fourth layer which are not covered with the resin layer; and a common electrode covering the first EL layer, the second EL layer, and the resin layer are formed.
