CHOLESTERIC LIQUID CRYSTAL COMPOSITION, LIQUID CRYSTAL DISPLAY PANEL, AND PREPARATION METHODS THEREFOR

WIPO Patent Application WO/2017/148025

A1

Provided are a cholesteric liquid crystal composition and a high-contrast liquid crystal display panel containing same, as well as preparation methods therefor. The cholesteric liquid crystal composition comprises a block copolymer and cholesteric liquid crystal. The block copolymer comprises a block A and a block B. The block A contains a chiral group M1 and the block B contains a chiral group M2. The cholesteric liquid crystal has at least two different pitches. The display panel comprises an array substrate and an opposed substrate that are cell-assembled, as well as a liquid crystal layer disposed between the array substrate and the opposed substrate, wherein the liquid crystal layer comprises the cholesteric liquid crystal composition. The liquid crystal layer can reflect, in a planar texture state, light of at least two wavelengths in a visible light area.
