摘要：

An electric optical system, wherein outsides of transparent upper and lower substrates in a bend cell are placed cross-nicolly between (one or more than one) birefringent film(s) and (two or more than two) polarized plates, and wherein the said substrates facing each other have such a relationship that a pre-tilt direction of liquid crystal molecules in one substrate interface and a pre-tilt direction of liquid crystal molecules in the other substrate interface of the substrates being planar symmetrical positions against center planes of both substrates, optionally with an active switch element formed on either transparent substrate in matrix form, as well as wherein there is used an oriented memberane made of a liquid crystal compound etc. expressed by the formula 1 and/or the formula 5 as the above-mentioned liquid crystal molecules.
