Abstract

A liquid crystal display element characterized by having an orientation controlling film containing a uniformly dispersed spacer therein on one inside surface of electrode substrates shows only a slight deviation in changes of the distance between the two electrode substrates even in the case of a large-size element. Such a liquid crystal display element can be produced by coating a mixture of a film forming material, a spacer and a solvent on one surface of an electrode adhered to one substrate, dried and baked, followed by conventional display element producing procedures.
