Abstract

A liquid crystal display apparatus comprises a liquid crystal display element comprising an active matrix substrate having an active element for each picture element electrode, a counter electrode substrate provided with a counter electrode and a liquid crystal and solidified matrix composite material, disposed between the active matrix substrate and the counter electrode substrate, which includes a nematic liquid crystal dispersed and held in a solidified matrix, said 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 doesn't coincide with the latter to thereby cause the scattering of light, and a driving circuit to drive the liquid crystal display element, wherein plural kinds of voltage is selectively applied to the picture elements in order to display specified states of the picture elements of the display element.
