Polarized light reflecting element, liquid crystal display element using the same, and method of manufacturing polarized light reflecting element

摘要

A polarized light reflecting element includes a plurality of stacked cholesteric liquid crystal layers. Each cholesteric liquid crystal layer is polymerized and has a helical liquid crystal molecule array and a helical axis that extends substantially in the normal direction. The in-plane mean value alpha of the respective helix angles of liquid crystal molecules is nearly npi (n=1, 2, 3, . . . ). The cholesteric liquid crystal layers have their liquid crystal molecules continuously oriented on the interfaces between them, and form one smooth helical structure as a whole.
