-1- ABSTRACT A liquid crystal display device has a pair of transparent electrodes and a composite film having continuous pores of a polymer matrix filled with a liquid crystal material. The polymer matrix is made of (a) a cross-linked material prepared through an addition reaction of a carboxyl group- containing acrylonitrile/butadiene copolymer with an oxazoline compound, or (b) a polyimide resin. The resulting device has improved light transmittance contrast, and improved resistance to having its contrast characteristics impaired by heat.
