Abstract

A display has a liquid crystal composite layer interposed between a pair of substrates on which electrodes-are formed. The liquid crystal composite layer is comprised of a matrix and liquid crystal droplets dispersed therein. The matrix is composed of an inorganic oxide or its gel of the formula MOx (M: one or more metal elements selected from, La, Y, Ti, Zr, Hf, V, Nb, Ta, Al, Ga, Ge, Pb or Sb; x: half of the total valence number of the one or more metal elements), or a mixture thereof with an inorganic oxide or its gel of formula ABOx (A: one or more metal elements selected from alkaline earth metals, rare earth metals or Pb; B: one or more metal elements of transition metals; x: a number larger than 0 (zero) and not-larger than 3). A polymer soluble in polar solvent may be added to adjust the dielectric constant of the matrix.
