COMBINATION OF OPTICAL ELEMENTS

摘要

PURPOSE: An optical retardation film used in such a combination of optical elements and to a liquid crystal display comprising such a combination of optical elements are provided. CONSTITUTION: A combination of optical elements comprise at least one optical retardation film and at least one broadband reflective polarizer, characterized in that the optical retardation film is comprising at least one layer of an anisotropic polymer material having an optical symmetry axis substantially parallel to the plane of the layer, the optical retardation film being obtainable by polymerization of a mixture of a polymerizable mesogenic material comprising: a) at least one reactive mesogen having at least one polymerizable functional group; b) an initiator; c) optionally a non-mesogenic compound having two or more polymerizable functional groups; and d) optionally a stabilizer; and relates to an optical retardation film used in the combination of optical elements and to a liquid crystal display comprising the combination of optical elements.
