Abstract
A non-liquid crystal organic compound having positive dielectric anisotropy is mixed with a nematic liquid crystal composition having negative dielectric anisotropy to obtain a nematic liquid crystal composition having positive dielectric anisotropy, which is used as an electro-optical element. Thus, the present invention aims at development of new use of the materials.
