Abstract
A liquid crystal display element comprises a pair of substrates provided with electrodes and a liquid crystal and solidified matrix composite material, disposed between the pair of substrates, which includes a nematic liquid crystal dispersed and held in a solidified matrix, the nematic liquid crystal being such that the refractive index of the liquid crystal is changed depending on states of applying a voltage wherein in a state, the refractive index of the liquid crystal substantially coincides with that of the solidified matrix to thereby pass light, and in the other state, the former does not coincide with the latter to thereby cause the scattering of light, wherein the refractive index anisotropy .DELTA.n of the liquid crystal used is 0.18 or higher, and the dielectric anisotropy .DELTA..epsilon..sub.LC of the liquid crystal used satisfies the relation of 5<.DELTA..epsilon..sub.LC <13.
