    Abstract: The present invention provides a moth-eye film that is not likely to cause condensation on the surface. A moth-eye film including: a resin composition that, when formed into a flat film, has a contact angle with water of larger than 5° but smaller than 31.3°, the contact angle measured between a surface of the flat film and a droplet of water dropped onto the surface of the flat film, after 100 msec from contact of the droplet and the surface.

    Abstract: 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.
