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.

A manufacturing method of a display device, including:
- preparing a substrate including a plurality of panel portions each of which includes a display area, and a margin area around the panel portions;
- forming a plurality of lower electrodes including a first lower electrode in the display area;
- forming a rib comprising a plurality of pixel apertures including a first pixel aperture overlapping the first lower electrode;
- forming a first partition including a first lower portion and a first upper portion comprising an end portion which protrudes from a side surface of the first lower portion in the margin area;
- forming a first stacked film including a first organic layer which is in contact with the lower electrodes through the pixel apertures, and a first upper electrode which covers the first organic layer;
- and
- forming a first sealing layer with an inorganic insulating material which covers the first stacked film, wherein
- the first stacked film is formed in an entire of the substrate and is divided into a plurality of portions by the first partition,
- the first sealing layer continuously covers the plurality of portions,
- an end portion of the substrate is spaced apart from an end portion of the first sealing layer as seen in plan view, and
- the first stacked film is exposed from the first sealing layer in an area between the end portion of the substrate and the end portion of the first sealing layer.
