Abstract
A liquid crystal device comprising a first base plate which has projections thereon and has been subjected to a uniaxial orientation treatment, a second base plate disposed oppositely spaced from the first base plate with the projections therebetween as spacers, and a liquid crystal disposed between the first and second base plates. The projections have a section taken in parallel with the base plates, and the section has a side with a length of 0-20 .mu.m in a direction perpendicular to the uniaxial orientation treatment. The projections may be in the form of rectangular pillars, cylindrical pillars, oval pillars, or hexagonal pillars.
