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.
