Abstract
According to one embodiment, a manufacturing method of a display device includes preparing a processing substrate, forming an organic layer, and forming an etching stopper layer on the organic layer. The forming the etching stopper layer includes carrying the processing substrate into a chamber, inside the chamber, emitting a material for forming the etching stopper layer from an evaporation source which inclines with respect to a normal of the processing substrate, and conveying the processing substrate while rotating the processing substrate in a plane orthogonal to the normal, and depositing the material emitted from the evaporation source on the processing substrate.
