Abstract: The present invention provides a mirror plate capable of suppressing the occurrence of orange peel-like unevenness. The mirror plate includes a mirror film including a mirror layer and an adhesive layer; and a substrate. The adhesive layer is attached to one surface of the substrate. The one surface of the substrate has an arithmetic average roughness of less than 0.03 μm. The mirror film includes no hard coat layer containing cured resin. The thicknesses of the mirror layer and the adhesive layer have a relation satisfying: tA/tM≤0.18, where tM represents the thickness of the mirror layer and to represents the thickness of the adhesive layer.

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.
