ABSTRACT:
An improved liquid crystal device is described. The distance between a pair of substrates is kept constant by means of spacers interposed therebetween. The spacers consist of two kinds of spacers. One kind of spacers is fusable and functions to prevent the distance from expanding. The other kind of spacers is non-fusable and functions to prevent the distance from contracting.
