The present invention provides a method for producing an optical film excellent in anti-fouling properties and scratch resistance as well as anti-reflection properties. The method includes the steps of: (1) applying a lower layer resin and an upper layer resin; (2) forming a resin layer having the uneven structure on a surface thereof by pressing a mold against the lower layer resin and the upper layer resin from the upper layer resin side in the state where the applied lower layer resin and upper layer resin are stacked; and (3) curing the resin layer, the lower layer resin containing at least one kind of first monomer that contains no fluorine atoms, the upper layer resin containing a fluorine-containing monomer and at least one kind of second monomer that contains no fluorine atoms, at least one of the first monomer and the second monomer containing a compatible monomer that is compatible with the fluorine-containing monomer and being dissolved in the lower layer resin and the upper layer resin.

The present invention relates to a guide apparatus for installing a protective film on a front surface of a portable electronic device. The guide apparatus according to one embodiment includes: a receiving plate on which the portable electronic device is placed such that a rear surface of the portable electronic device is in contact with the receiving plate; and a retainer for retaining both end corners of a first side of the portable electronic device such that the retainer is in close contact with the first side of the portable electronic device placed on the receiving plate. The retainer is constructed to have a plurality of retaining lengths on the receiving plate.

Thin-film devices, for example electrochromic devices for windows, and methods of manufacturing are described. Particular focus is given to methods of patterning optical devices. Various edge deletion and isolation scribes are performed, for example, to ensure the optical device has appropriate isolation from any edge defects. Methods described herein apply to any thin-film device having one or more material layers sandwiched between two thin film electrical conductor layers. The described methods create novel optical device configurations.
