Abstract

According to one embodiment, a manufacturing method of a display device includes preparing a processing substrate by forming a lower electrode, forming a rib, and forming a partition including a lower portion and an upper portion, forming an organic layer on the lower electrode, forming an upper electrode on the organic layer, forming a first transparent layer on the upper electrode, and forming a second transparent layer on the first transparent layer. The first transparent layer and the second transparent layer are formed of organic materials different from each other. A refractive index of the second transparent layer is less than a refractive index of the first transparent layer.
