Abstract

PURPOSE:To obtain a liquid crystal cell exhibiting good orientation having no domains by rotating either or a cylindrical sleeve or a magnets to attract magnetic powder on the sleeve surface and rubbing a liquid crystal with the magnetic brush formed by this. CONSTITUTION:In a magnet roll conisting of a cylindrical sleeve 21 and magnets 22, the magnet roll is rotated to attract magnetic powder magnetically to the surface of the sleeve 21, whereby a magnetic brush 23 is formed. In the surface of a liquid crystal cell substrate 24 is rubbed with a rotating magnetic brush 23, microflaws are formed on the surface of the substrate 24, by which the liquid crystal in the liquid crystal cell is oriented. At this time, if the magnetic powder is selected to a suitable amt. and a blade 34 for regulating the length of the ears of a magnetic brush 33 is provided, the magnetic brush 33 of uniform length is formed on the sleeve 31 surface of the magnet roll. It is possible to perform uniform orientation treatment by using such magnetic brush 33.
