Polymer dispersed liquid crystal with polymer glass transition above 50 DEG C. and low isotropic transition shift

摘要

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 DELTA T is 25 DEG C. or less, and a glass transition temperature Tg of the polymer resin composition is 60 DEG C. or more, the value DELTA T being defined as a difference between a phase transition temperature TCI 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.
