Abstract

See full text

Example embodiments relate to an optical shutter including a first polarization filter having a nanopore-cholesteric liquid crystal layer, which includes a cholesteric liquid crystal matrix and a plurality of liquid crystal nanopores embedded in the cholesteric liquid crystal matrix, and having a reflective wavelength band that varies according to electrical control, and a second polarization filter that is parallel to the first polarization filter, includes a nanopore-cholesteric liquid crystal layer, which includes a cholesteric liquid crystal matrix and a plurality of liquid crystal nanopores embedded in the cholesteric liquid crystal matrix, and has a reflective wavelength band that varies according to electrical control.
