Abstract
The invention has an object to provide a liquid crystal composite capable of sufficiently reducing the scattering of light in a focal conic state, a liquid crystal display element excellent in improvements of a color balance and a contrast, and electronic paper using the same. The content of a chiral material is higher in a cholesteric liquid crystal LCg for G than in a cholesteric liquid crystal LCb for B, and is higher in a cholesteric liquid crystal LCr for R than in the cholesteric liquid crystal LCg for G. The cholesteric liquid crystal LCr for R is prepared by mixing about 5 wt % of a chiral material CHlof an L-form with a base liquid crystal of an R-form, which contains 27 wt % of CHrof the R-form exhibiting a liquid crystallizability for a nematic liquid crystal LCn, and 3 wt % of a chiral material CHrof the R-form exhibiting no crystallizability.
