Abstract: The present invention provides a laminated retardation optical element that never lowers contrast and thus never degrades display performance even when placed between a liquid crystal cell and a null/4 retardation film. In a liquid crystal display 90, a laminated retardation optical element 10 is placed between a polarizer 102A on the incident side and a liquid crystal cell 104, and a null/4 retardation film 102C is placed between a polarizer 102B on the emergent side and the liquid crystal cell 104. The laminated retardation optical element 10 comprises: a null/4 retardation layer 14 having the function of bringing, to light that passes through this retardation layer, a phase difference corresponding to a quarter of the wavelength of the light; and a C plate-type retardation layer 16 that acts as a negative C plate. The null/4 retardation layer 14 and the C plate-type retardation layer 16 are laminated to a transparent substrate 12 in the order mentioned, and are optically bonded to each other. The null/4 retardation layer 14 comprises as its main component a horizontally-aligned, cross-linked nematic liquid crystal, while the C plate-type retardation layer 16 comprises as its main component a cross-linked chiral nematic liquid crystal (a cross-linked nematic liquid crystal and a cross-linked chiral agent) or cross-linked discotic liquid crystal.

Abstract: An improved flat panel display provides reduced reflection of incident light on the display to improve display visibility. The display includes a transparent top cover panel such as glass which is bonded or laminated to the display polarizer. The outer viewing surface of the top cover panel carries a plurality of integral surface features defined in the surface, which may comprise etched bumps or micro-machined tetrahedron-shaped protuberances that may be truncated, smoothed, and/or variously oriented and sized to further reduce incident light reflectivity. A multi-layer HEA coating on the featured surface defines a graduated transition layer with an index of refraction that gradually, and preferably smoothly, varies from layer to layer of the HEA coating from the index of refraction of the top cover panel to the index of refraction of the ambient air or other material which the outermost viewable surface of the display presents an image to an observer or viewer.

Abstract: An object of the present invention is to eliminate drawbacks of conventional multi-layered antireflection films, that is, that a lot of time is required in the formation of a transparent conductive thin film and a low-refractive index layer leading to low processing speed, the corrosion resistance of the transparent conductive thin film is unsatisfactory, and the reflectance over the whole visible light region is not constant. This object can be attained by adopting a structure comprising: a transparent layer 3, with a pencil hardness of H or more, formed of a cured product of an ionizing radiation-curable resin composition; provided on one side of the transparent layer 3, a concave-convex portion 2 comprising innumerable fine concaves and convexes provided at a pitch of not more than the wavelength of light; a transparent substrate film 1 optionally provided on the transparent layer 3 on its side remote from the concave-convex portion 2; and a cover layer, having a lower refractive index than the transparent layer, preferably provided on the fine concaves and convexes.
