1. A planar light emitting device, comprising:
an organic electroluminescence element including a first surface and a second surface which are opposite surfaces in a thickness direction of the organic electroluminescence element, the organic electroluminescence element being configured to emit light via the first surface; a formation substrate which is of a resin material with a light transmissive property allowing light emitted from the organic electroluminescence element to pass therethrough, and is adjacent to the first surface of the organic electroluminescence element; a light outcoupling structure provided to the formation substrate and suppressing reflection of light emitted from the organic electroluminescence element at a surface of the formation substrate; a first moisture preventer which has a moisture proof property, and is over the second surface of the organic electroluminescence element to cover the organic electroluminescence element; and a second moisture preventer which has a moisture proof property, and covers the formation substrate to prevent moisture from passing through the formation substrate and reaching the first surface of the organic electroluminescence element, the second moisture preventer including an overlap which overlaps the first surface in the thickness direction of the organic electroluminescence element, a whole of the formation substrate being on a surface of the overlap, and the overlap being of material with a light transmissive property allowing light emitted from the organic electroluminescence element to pass therethrough. |
