Abstract: A liquid crystal display cell, wherein orientation films are made of an organic polymer such as polyimide, polyamide, liquid crystal polymer having one or more mesogen groups in a main chain or side chain and produced by spreading an organic polymer solution on a water surface, is excellent in memory properties and contrast and generates no static electricity, no short circuit between electrodes and no breaking of electrodes.

Abstract: Disclosed is a process in which a spherical electrophotographic toner containing a colorant and having a particle size suitable for the electrophotography is directly formed in the polymerization process for formation of a binder resin. If a reaction medium capable of dissolving a monomer but incapable of dissolving a formed polymer is used and polymerization is carried out in the presence of a radical polymerization initiator in the state where the monomer, the colorant and other additives are dissolved or dispersed in the reaction medium, an electrophotographic toner having a desired particle size is obtained. According to this process, the particle size of the colored resin is stably controlled to 1 to 30 .mu.m suitable for a toner in the polymerization process, and the particle size distribution is very sharp.
