Abstract
A functional film of the present invention includes a support body of which a retardation value is less than or equal to 300 nm; a protective inorganic layer which is formed on the support body; one or more combinations of an inorganic layer and an organic layer which are formed on the protective inorganic layer; and a mixed layer having a thickness of 1 to 100 nm which is formed between the support body and the underlying inorganic layer, and is mixed with a component of the support body and a component of the protective inorganic layer.
Claims12
A functional film, comprising:
- a support body of which a retardation value is less than or equal to 300 nm;
- a protective inorganic layer which is formed on the support body;
- one or more combinations of an inorganic layer and an organic layer as a base for the inorganic layer, the combinations being formed on the protective inorganic layer;
- and
- a mixed layer having a thickness of 1 nm to 100 nm which is formed between the support body and the protective inorganic layer, and is mixed with a component of the support body and a component of the protective inorganic layer,
- wherein each of the protective inorganic layer and the inorganic layer is a silicon nitride layer.
