Abstract
According to the present invention, there is provided a liquid crystal panel frame used for a liquid crystal display which comprises a pair of opposed substrates, a pair of electrodes formed on each of those substrates, a plurality of rectilinear barrier members provided at predetermined intervals between both substrates and an orientation film formed on said substrates and being subjected to a rubbing process. Each barrier member extends in substantially parallel to the rubbing direction. By adhering each barrier member to the substrate opposed thereto, a plurality of narrowly partitioned rectilinear spaces in which portions other than an aperture formed at the end portion thereof through which the liquid crystal passes are sealed against liquid. Ferroelectric or anti-ferroelectric liquid crystals are encapsulated into each of those rectilinear spaces to form a liquid crystal panel assembly. After the encapsulated liquid crystal is held to a high temperature, that liquid crystal panel assembly is sequentially cooled down from one end of the rectilinear space toward the other end thereof under the condition in which the temperature gradient is kept appearing along the rubbing direction, to thereby obtain a defect-free orientated chiral smectic phase in the liquid crystal.
