PROBLEM TO BE SOLVED: To provide a the optical material-protecting laminate integrally laminated with a protective film, and having high transparency and high barrier property with respect to oxygen, water vapor or the like, which is used as a surface base material which is easily handled, has satisfactory suitability for working and does not deteriorate the barrier property, in particular, even when performing protective film peeling upon usage, and to provide an electroluminescence optical element and an electrophoretic display panel which use the optical material-protecting laminate. SOLUTION: The optical material-protecting laminate which is transparent and has the barrier property, is constituted so that the protective film which is peeled and removed during usage in a composite form of a pressure-sensitive adhesive layer and a pressure-sensitive base material is laminated integrally with the surface base material which has the barrier property and constitutes the surface of a display element by itself, wherein the surface base material includes a transparent vapor deposition layer made of inorganic oxide deposited on the transparent base material as a transparent barrier layer and the peeling strength of the adhesive layer is 100 mN/25 mm or less with respect to the surface base material. And, the electroluminescence light emitting element and the electrophoretic display panel which are provided with the optical material-protecting laminate are also provided.
