Abstract: A mirror device has a light-transmissive substrate and at least one organic EL element supported on the back surface of the light-transmissive substrate, and emits light from the front surface of the light-transmissive substrate. The organic EL element has an organic layer containing a light-emitting layer layered between a light-transmissive electrode and a reflection electrode that are opposite to each other. The light-transmissive electrode is formed on the light-transmissive substrate. The mirror device has a plurality of metal mirror surface portions that each have an area smaller than the area of the light-transmissive electrode and are distributed and disposed on the front surface of the light-transmissive substrate so as to be opposite to the light-emitting layer.

Abstract: A light emitting portion (200) is formed on a first surface of a substrate (100) (upper surface of the substrate (100) in an example illustrated in FIG. 1). A sealing member (300) seals the light emitting portion (200). In addition, the substrate (100) includes a first resin layer (110), a first inorganic layer (120), and a second resin layer (130). The first resin layer (110) is formed of a first resin material. The second resin layer (130) is formed of the first resin material, and is positioned closer to the first surface side of the substrate (100) than the first resin layer (110). The first inorganic layer (120) is positioned between the first resin layer (110) and the second resin layer (130).
