摘要

PROBLEM TO BE SOLVED: To provide a device for rubbing alignment treatment of an alignment layer ensuring uniform alignment and preventing release of a rubbing material. SOLUTION: Alignment controllability over a liquid crystal is given to the alignment layer 7 by rubbing the alignment layer 7 with a rubbing material 3 wound around the outer periphery of the roller 1. The cross sectional shape of the roller 1 is made elliptic and the rubbing joint part 4 at both end parts of the rubbing material 3 wound around the outer periphery thereof is positioned on the place corresponding to the minor axis of the ellipse.
