Abstract
A cholesteric liquid crystal display device includes: a plurality of pixel units arranged two-dimensionally between two transparent substrates. Each of the plurality of pixel units includes a cholesteric liquid crystal layer having a single-layer structure. The cholesteric liquid crystal layer includes: a liquid crystal molecule; a chiral dopant; and an optically polymerizable polymer. The chiral dopant is mixed with the liquid crystal molecule to form a cholesteric phase and has a solubility that varies with respect to the liquid crystal molecule according to temperature. The optically polymerizable polymer is cured to fix a helix pitch of the cholesteric phase.
