MULTILAYER FILM AND SUBSTRATE WITH MULTILAYER FILM USING THE MULTILAYER FILM

摘要

PROBLEM TO BE SOLVED: To provide a multilayer film which has optical characteristics approximate to a multilayer film using a silica film as the outermost layer, and which can prevent small scratches from being formed on the surface of the film. SOLUTION: A multilayer film 16 has a high refractive-index film and a low refractive-index film laminated alternately on the surface of a substrate 11. The refractive-index of the outermost layer is 1.5 or less, and it is formed from a film which has a better scratch resistance than the silica film.
