The present invention proposes an optical device according to claim 1. The optical device comprises a glazing with a top outer surface and a bottom outer surface extending between a first lateral end face and a second lateral end face. The glazing comprises at least one outer layer made of glass or of an optically clear polymer material. The glazing comprises a photoluminescent structure having one or more photoluminescent domains. The optical device comprises a light source for injecting excitation light into said glazing, said excitation light being suitable to excite the one or more photoluminescent domains to induce photoluminescence of the one or more photoluminescent domains. The light source is optically coupled to the glazing to inject light such that the light injected at the first lateral end face of the glazing so that the light is guided to propagate through the glazing from the first lateral end face to the second lateral end face, the glazing forming a waveguide between the top surface and the bottom surface by total internal reflection of the light at the top outer surface and the bottom outer surface, to induce photoluminescence of the one or more photoluminescent domains.

The first aspect of the present invention aims to provide an interlayer film for laminated glass, an interlayer film for luminescent laminated glass, and a laminated glass including the interlayer film for laminated glass which are significantly suppressed while containing an aromatic compound such as a salicylic acid compound or a benzophenone compound. The second aspect of the present invention aims to provide an interlayer film for laminated glass which enables display of high luminance images under irradiation with light and inhibits reduction in the luminance of images even after use for a long period of time, and a laminated glass including the interlayer film for laminated glass. The first aspect of the present invention relates to an interlayer film for laminated glass containing: a thermoplastic resin; an aromatic compound that has a structure capable of coordinating with a metal; and an antioxidant, the antioxidant being at least one antioxidant selected from the group consisting of a phenolic compound, a phosphoric acid compound, and a sulfur compound. The second aspect of the present invention relates to an interlayer film for laminated glass including a luminescent layer that contains a thermoplastic resin, a luminescent material having a terephthalic acid ester structure, and a benzotriazole ultraviolet absorber, the luminescent layer containing the benzotriazole ultraviolet absorber in an amount of 0.05 to 10 parts by weight based on 1 part by weight of the luminescent material having a terephthalic acid ester structure.
