Abstract: A plurality of transmissive organic EL panels in a light emitting device each include: a first transparent substrate; a second transparent substrate; an organic EL element; a resin sealant; a group of first terminals; and a group of second terminals. The group of first terminals and the group of second terminals are alternately arranged in a direction along an outer perimeter of the first transparent substrate. The plurality of transmissive organic EL panels are arranged in a two-dimensional array. In adjacent transmissive organic EL panels, the group of first terminals and the group of second terminals are inversely arranged. A first terminal among the group of first terminals of one of the adjacent transmissive organic EL panels and an overlapping second terminal among the group of second terminals of the other of the adjacent transmissive organic EL panels are electrically connected via a connector.

Abstract: An optical switching device includes: a plurality of optically variable bodies that are each variable in a degree of an optical state according to electric power; and an optical adjustment layer located between the plurality of optically variable bodies. The optically variable bodies each include: a pair of substrates; a pair of electrodes located between the pair of substrates; and an optically variable layer located between the pair of electrodes. The optical adjustment layer adheres the plurality of optically variable bodies in sheet form in a thickness direction, and adjusts a refractive index between respective substrates of adjacent optically variable bodies. The pair of electrodes have an exposed surface for supplying the electric power. An adhesion strength of the optical adjustment layer to the substrates is higher than an adhesion strength of the optically variable layer to the electrodes.
