Abstract: PROBLEM TO BE SOLVED: To solve a problem that transmissivity of light passing through plural thin films having different refractive indexes decreases due to light reflection at the interface of the thin films, when a light-emitting element is sealed, for example, in a general way using a laminate structure of the thin films in consideration of influence of stress, causing different materials to be laminated to form the thin films having different refractive indexes.SOLUTION: An organic EL element 150 is used, for example, as a light-emitting element. An antireflection layer 138 as a third layer for at least some wavelengths of emitted light is sandwiched between a barrier layer 137 as a first layer for preventing intrusion of water or oxygen into the organic EL element 150 and an organic intermediate layer 139 as a second layer for relaxing stress of the barrier layer. The antireflection layer 138 has a refractive index n between the refractive index of the first layer and the refractive index of the second layer; and has a thickness of λ/4n when λ represents a wavelength of the light-emitting element, whereby a reflection loss at the interface between the barrier layer 137 and the organic intermediate layer 139 can be reduced.
