ABSTRACT:
An antiferroelectric liquid crystal composite material comprising an organic polymer and an antiferroelectric liquid crystal material, both being in the dispersed state; a process for preparing a liquid crystal element including a step of mixing an organic polymer and an antiferroelectric liquid crystal material; and a liquid crystal element having such a structure that the above-mentioned antiferroelectric liquid crystal composite material is sandwiched between a pair of electrodes are provided. According to the present invention, there can be obtained a liquid crystal element which is available at a low price, quick in the electrooptical response, free from occurrence of switching failure and is able to make a large display screen.
