Abstract

In a liquid crystal display device comprising two glass substrate plates positioned in parallel with each other at a nearly constant interval and a liquid crystal interposed between said glass substrate plates, an electrode being provided on each of the opposite surfaces of said glass substrate plates and a voltage being applied between said electrodes, "haze" which appears at the display surface can be removed by using a liquid crystal composition containing one or more additives capable of controlling the orientation of the liquid crystal molecules (namely, capable of forming a perpendicular orientation phase).
