Abstract: According to one embodiment, a manufacturing device includes a main manufacturing line and a sub-line. The main manufacturing line includes a preprocessing portion, an in-line first evaporation device, a first CVD device for forming a first inorganic insulating layer of a sealing layer, a dry etching device for reducing a thickness of the first inorganic insulating layer, and a second CVD device for forming a second inorganic insulating layer of the sealing layer. The sub-line forms a detour which is different from the main manufacturing line as a conveyance path for conveying a processing substrate. The main manufacturing line and the sub-line form a loop conveyance path.
