Abstract
Liquid crystal films which are stable to light, moisture and heat, and which have an improved response time and viewing angle are provided by combining ferroelectric liquid crystals and a polymer matrix. The invention further provides for liquid crystal display elements utilizing the liquid crystal films of the invention. Still further, the invention provides methods of producing the liquid crystal films. According to the invention, liquid crystalline polymers having optical anisotropy as a polymer matrix and functional side chain radicals having an asymmetric carbon atom and dipole moment in the polymer matrix are matched with the dipole moment of the ferroelectric crystals.
