Abstract:
The present invention includes an optical element of which an oblique tint change can be improved in a case of the optical element is incorporated to a liquid crystal display device, a method of manufacturing an optical element, and a liquid crystal display device. The optical element includes: a reflection polarizer which is formed of a discotic liquid crystal compound and in which a cholesteric liquid crystalline phase is immobilized, in which, in the reflection polarizer, a front retardation value Re satisfies 0 nm≤Re
