Abstract
A method of manufacturing a display device includes forming a display portion on a substrate, and forming an encapsulation portion for sealing the display portion. The forming of the encapsulation portion includes forming a first layer covering the display portion, forming a second layer on the first layer, and forming a third layer on the second layer. The first layer is formed by maintaining a distance between an upper surface of the display portion and a mask by a first interval. The second layer is formed by maintaining a distance between an upper surface of the first layer and the mask by a second interval that is different from the first interval. The third layer is formed by maintaining a distance between an upper surface of the second layer and the mask by a third interval that is different from the second interval.
