DISPLAY DEVICE AND MANUFACTURING METHOD OF DISPLAY DEVICE

According to one embodiment, a manufacturing method of a display device includes preparing a processing substrate by forming a lower electrode, forming an inorganic insulating layer, and forming a partition including a lower portion and an upper portion, forming an organic layer including a light emitting layer, forming an upper electrode, forming a cap layer, forming a first sealing layer, and forming a resin layer. The process of forming the organic layer, the upper electrode and the cap layer is an evaporation process using the partition as a mask in a vacuum environment. The process of forming the resin layer includes a process of applying a resinous material in an air atmosphere.
