| Popis: | We developed an anisotropic nano-imprinting technique, which combines the exposure of ultraviolet light, to fabricate a patterned optical film of a liquid crystalline polymer (LCP). The nano-imprinted LCP film has two-fold functionality of an in-cell retarder and an alignment layer of liquid crystal (LC) molecules. In addition to the geometrically generated microgrooves, the anisotropic surface interactions of the LCP acquired at a nano-scale level during the imprinting process results in the LC alignment on the patterned LCP film without any surface treatment. The nano-imprinted, quarter wave LCP was implemented into a LC cell which produces half-wave retardation under crossed polarizers. |
