Production of liquid crystal device including aligning treatment by rubbing

摘要

In a successive rubbing treatment for providing a large number of substrates each having an alignment control layer with a uniaxial alignment axis for aligning a liquid crystal, a plurality of substrates are rubbed alternately with one or the other side of pile yarn planted on a rubbing cloth wound about a roller. A liquid crystal is disposed between a pair of substrates which are selected from the plurality of substrates thus treated by rubbing. By this process, a larger number of substrates can be imparted with a uniaxial alignment control power without causing a lowering in the alignment control power.
