There is provided an optical body with improved antireflection capability, a display device, and a method for manufacturing an optical body, the optical body including: a first concave-convex structure formed on a surface of a base material; and a second concave-convex structure superimposed on the first concave-convex structure. An average concave-convex period of the first concave-convex structure is larger than a wavelength in a visible light region, an average concave-convex period of the second concave-convex structure is less than or equal to the wavelength in the visible light region, and projecting parts of the second concave-convex structure extend in a direction normal to a flat plane of the base material.

There is provided a transparent film for a face protection shield in which transparency is enhanced and visibility from a non-wearer is also enhanced, the transparent film for a face protection shield including: a transparent base material having flexibility; and a transparent resin layer configured to be laminated on at least one of surfaces of the transparent base material, the transparent resin layer having on a surface a plurality of structural bodies including concavities or convexities provided at a pitch of less than or equal to a visible light wavelength. A refractive index of the transparent base material is different from a refractive index of the transparent resin layer, and an interface between the transparent base material and the transparent resin layer has a concave-convex shape.

A retardation compensatorfor compensating for residual retardation of a liquid crystal panelincludes a retardation compensating platehaving birefringence. An in-plane retardation Rof the retardation compensating plateand an in-plane retardation Rof the liquid crystal panelsatisfy a relationship of 1&#x3c;R/R&#x2266;10, thereby allowing changes in the amount of compensated retardation among rotation angles occurring when the retardation compensating plateis set with respect to the liquid crystal panelto be confined within narrow limits. Therefore, the contrast can be adjusted readily, and variations in residual retardation among the individual liquid crystal panelscan be accommodated flexibly.

The present invention provides a non-aqueous electrolyte secondary cell including: a cathode containing a manganese oxide or a lithium-manganese composite oxide; an anode containing a lithium metal, a lithium alloy, or a material capable of doping/dedoping lithium; and an electrolyte containing at least two electrolyte salts, one of which is LiBF contained in the range from 0.005 mol/l to 0.3 mol/l. This enables to increase the cycle characteristic, preventing deterioration of the cell characteristic caused by a repeated use.
