Abstract: A manufacturing method of a display device including a pixel region including a plurality of pixels each including a light emitting element and a terminal region provided outside the pixel region and including connection terminals; the method comprising: forming a recessed portion in a part of a top surface of each of the connection terminals; forming a first inorganic insulating layer, an organic insulating layer, and a second inorganic insulating layer sequentially in the pixel region and continuously in the terminal region; and etching the first inorganic insulating layer and the second inorganic insulating layer in an area where the first inorganic insulating layer and the second inorganic insulating layer are stacked directly, the area being on the top surface except the recessed portion.

Abstract: A base body including a plurality of first regions and a second region having a shape surrounding each of the first regions is prepared. A resin layer is formed in the plurality of first regions while avoiding the second region. A buried layer having a moisture-proof property higher than the resin layer is formed in the second region. A functional layer including a self-emitting element layer emitting light whose luminance is controlled for each of a plurality of unit pixels constituting an image is formed on the resin layer and the buried layer. The buried layer and the functional layer are cut along a line passing through the second region, so as to separate the resin layer into a plurality of portions respectively corresponding to the plurality of first regions.
