Beschreibung
Zusammenfassung:	An optical film which is formed from a thermoplastic resin, and wherein: the thermoplastic resin contains a hydrogenated block copolymer (G) that contains two or more polymer blocks (D) per molecule, said polymer blocks (D) being mainly composed of a cyclic hydrocarbon group-containing compound hydride unit (I) and one or more polymer blocks (E) per molecule, said polymer blocks (E) being mainly composed of a chain hydrocarbon compound hydride unit (II) or a combination of the unit (I) and the unit (II); and the thermoplastic resin satisfies G"/G' > 0.95 or ([eta]\|[epsilon] =2 - [eta]\|[epsilon] =1) > -1.0 * 104 Pa·s. In the formula, G' represents the storage elastic modulus of the thermoplastic resin; G" represents the loss elastic modulus of the thermoplastic resin; and ([eta]\|[epsilon] =2 - [eta]\|[epsilon] =1) represents the slope of the elongation viscosity of the thermoplastic resin.
