摘要： Disclosed are an anti-reflection structure, an imprint mold, methods for producing them and a display device capable of achieving appropriate visibility by forming regions different in reflection characteristics mixed in a film including a moth-eye structure, and sufficiently reducing reflection and sufficiently improving transmittance by the moth-eye structure. The anti-reflection structure includes a surface with an uneven structure composed of a transparent body and includes protrusions, the width between the tops of any pair of the adjacent protrusions being equal to or shorter than visible light wavelengths, the anti-reflection structure including a first region including a surface with the uneven structure, and a second region including a surface with a structure composed of a transparent body, the structure being different from the uneven structure and the second region in a plan view having a shape forming at least one selected from the group consisting of characters, symbols, and graphics.

摘要： Disclosed is a display device capable of suppressing the occurrence of interference fringe in an oblique direction. A front sheet is disposed in front of a display panel with an air layer interposed therebetween. A film is disposed on the front surface of the display panel or on the rear surface of the front sheet. The air layer has a thickness of ≦50 μm. The display panel and/or the front sheet can be warped. The thickness of the air layer varies within a range of 0 μm to 50 μm. Further, the film includes a moth-eye structure on a surface contacting the air layer. Finally, a reflectance at at least one wavelength within a range of 600 to 780 nm is smaller than a reflectance at a wavelength of 550 nm in the reflection spectrum of 5-degree specular reflection of the moth-eye structure.

摘要： 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.

摘要： A decorative film includes: a substrate; and a polymer layer including on a surface thereof an uneven structure provided with projections at a pitch not longer than a wavelength of visible light. The substrate contains a polycarbonate at least in its surface close to the polymer layer. The polymer layer is a cured product of a polymerizable composition. The polymerizable composition contains a release agent, a polyfunctional acrylate containing one or both of an ethylene oxide group and a propylene oxide group, and 2-(2-vinyloxyethoxy)ethyl acrylate. The polymerizable composition contains, in terms of active components, given proportions of the release agent and the 2-(2-vinyloxyethoxy)ethyl acrylate. The polymerizable composition contains, in terms of active components, a given total amount of the ethylene oxide group and the propylene oxide group in the polyfunctional acrylate and the 2-(2-vinyloxyethoxy)ethyl acrylate.
