<p>A thermally responsive liquid crystal display device having an excellent response speed and display performance, a uniform thickness distribution and a high film thickness and contrast, and consisting of a polymer dispersion type liquid crystal layer excellent in thermal cycle endurance. A polymer dispersion type liquid crystal layer consisting of a composition of polymer and liquid crystal is disposed on a heating element, a thermoplastic polymer is used for the polymer and a glass transition temperature (Tg) of the polymer and a phase transition temperature (TNI) satisfy the relation, -20°C≤(Tg-TNI)≤(20°C), the above polymer dispersion type liquid crystal layer being formed by laminating a plurality of polymer dispersion type liquid crystal films.</p> |
