ABSTRACT:
A liquid crystal display element has a pair of substrates and a liquid crystal material held between the substrates, the liquid crystal material containing a main liquid crystal material and an auxiliary liquid crystal material whose phase can be separated from the phase of the main liquid crystal material. The liquid crystal material exhibits the states of reflection, scattering and transmission upon receipt of an external stimulation. The particular construction of the liquid crystal material permits the display element to have a wide viewing angle and to exhibit excellent optical characteristics over wide wavelength range.
