ABSTRACT:
A liquid crystal display device according to the present invention includes a pair of electrode substrates and a polymer dispersed liquid crystal complex film interposed between the pair of substrates. The polymer dispersed liquid crystal complex film includes a liquid crystal composition and a polymer resin composition. It is ensured that a value a .DELTA.T is 25.degree. C. or less, and a glass transition temperature T.sub.g of the polymer resin composition is 60.degree. C. or more, the value .DELTA.T being defined as a difference between a phase transition temperature T.sub.CI of the liquid crystal composition between a liquid crystal phase and an isotropic liquid phase thereof and a phase transition temperature T.sub.matrix of the polymer dispersed liquid crystal complex film.
