초록 ▼

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 Dg of the polymer resin composition is 60°C. or more, the value DCI of the liquid crystal composition between a liquid crystal phase and an isotropic liquid phase thereof and a phase transition temperature Tmatrix of the polymer dispersed liquid crystal complex film.
