Optical film
First Claim
1. An optical film formed on a major surface of a substrate, the optical film comprising:
- a metal film formed on the major surface of the substrate; and
at least one set of a plurality of first island structures formed scattered as islands on a major surface of said metal film and a plurality of second island structures formed scattered as islands on the major surface of the substrate;
wherein said at least one set of the plurality of first island structures and the plurality of second island structures are made of at least one selected from the group consisting of metals and metal oxides having a different standard electrode potential to a metal of said metal film.

Abstract
An optical film which enables desired optical properties to be obtained easily, and enables the durability to be improved. A metal film 32 is formed on an inner major surface 12a of a glass substrate 12. A plurality of first island structures 33 is formed scattered as islands on an inner major surface 32a of the metal film 32. A plurality of second island structures 31 is formed scattered as islands on the inner major surface 12a of the substrate 12. At least one set of the plurality of first island structures 33 and the plurality of second island structures 31 are made of at least one selected from the group consisting of metals and metal oxides having a different standard electrode potential to a metal of the metal film 32.
