Provided are a foldable optical film with excellent impact resistance and with capability to improve design quality, and an image display device including the same. An aspect of the present invention provides a foldable optical filmwith a front surfaceA and a back surfaceB opposite to the front surfaceA, wherein optical filmincludes a hard coat layer, a resin layer, and a decorative layer; the hard coat layeris located closer to the front surfaceA than the resin layerand the decorative layerin the optical film; and the resin layerhas a film thickness of 10 μm or more, and the resin layerhas a Martens hardness of 1 MPa or more and 100 MPa or less.

Optical film and image display device

The present invention provides an optical layered body having excellent scratch resistance while having antireflective performance. The present invention relates to an optical layered body including a light-transmitting substrate; and at least an antiglare layer and a low refractive index layer disposed in the stated order on one surface of the light-transmitting substrate, wherein the low refractive index layer has an arithmetic average roughness Ra of projections and depressions of 4 nm or less and a ten-point average roughness Rz of the projections and depressions of 60 nm or less, where the Ra and the Rz are measured in any 5-μm square region of a surface of the low refractive index layer.

Optical layered body having specified average roughness and surface hardness

An embodiment of the present invention provides an optical film () including a light-transmitting base material (), a hard coat layer (), and an inorganic layer () in this order, wherein the hard coat layer () is in contact with the inorganic layer (), the hard coat layer () contains a binder resin (A) and inorganic particles (B), the hard coat layer () has a film thickness of 1 μm or more, and the hard coat layer () has an indentation hardness of 200 MPa or more.
