Title: LIGHT-EMITTING DEVICE
Abstract:
A light-emitting part (140) is positioned on a first surface (100a) side of a substrate (100). At least part of an organic layer is positioned between the light-emitting part (140) and an end part (100c) of the substrate (100). In an example shown in FIG. 1, this organic layer is an organic insulating film (150). In the following, a description is given with the organic insulating film (150) as the organic layer. However, this organic layer may be an organic layer (120) described hereinafter. A first covering layer (200) covers the light-emitting part (140) and the organic insulating film (150). An intermediate layer (300) is in contact with the surface on the opposite side of the first covering layer (200) from the substrate (100), and at least part of the intermediate layer (300) is positioned more to the end side (100c) than the organic insulating film (150). In addition, the intermediate layer (300) includes a desiccant. A second covering layer (400) is in contact with the surface of the intermediate layer (300) on the side opposite from the substrate (100).
