Abstract: An optical film including, in this order: a first layer containing a hydrogenated product of an aromatic vinyl compound-conjugated diene compound block copolymer; a second layer containing a norbornene-based polymer; and a third layer containing a hydrogenated product of an aromatic vinyl compound-conjugated diene compound block copolymer. Preferably, the hydrogenated product of the aromatic vinyl compound-conjugated diene compound block copolymer is a hydrogenated product of a styrene-isoprene copolymer. Preferably, a copolymerization ratio of styrene/isoprene in the hydrogenated product of the styrene-isoprene copolymer is 50/50 to 90/10.

Abstract: Provided is production of a resin film excellent in all of the folding resistance, the low water-absorption property, and the heat resistance. A resin film formed of a resin containing an alicyclic structure-containing polymer having crystallizability, the resin film having a folding endurance of 2,000 times or more, a water-absorption rate of 0.1% or less, and a heat-resistant temperature of 180° C. or higher; a resin film formed of a resin containing an alicyclic structure-containing polymer having crystallizability, the resin film having a crystallinity degree of the alicyclic structure-containing polymer of 10% or more, a folding endurance of 2,000 times or more, and a water-absorption rate of 0.1% or less, and a smooth surface; and production method thereof.
