摘要：
An optical body includes an optical element, an alignment layer disposed on the optical element, and a liquid crystal layer disposed on the alignment layer. The liquid crystal layer has a retardation (R) at all wavelengths (λ) from 400 nm to 700 nm equal to a formula R=λ/4±20 nm. The liquid crystal layer can include from 85 to 99 phr of an achiral liquid crystal material, from 1 to 15 phr of a chiral nematic liquid crystal material, and a surfactant.
