Abstract: According to one embodiment, a manufacturing method includes preparing a substrate including panel portions and a margin area, forming lower electrodes, forming a rib, forming a first partition in the margin area, forming a first stacked film, and forming a first sealing layer. The first stacked film is formed in an entire of the substrate and is divided into portions by the first partition. The first sealing layer continuously covers these portions. An end portion of the substrate is spaced apart from an end portion of the first sealing layer. The first stacked film is exposed from the first sealing layer in an area between the end portions of the substrate and the first sealing layer.
