Abstract:
A rubbing treatment apparatus comprising:a rubbing roller having a rotation axis and including a rubbing cloth wound around a surface thereof to be adhered, the rubbing cloth including pile yarns which are implanted at cyclic intervals in two directions perpendicular to each other,the rubbing roller being for contacting a surface of a film-to-be-processed which is formed so as to cover a plurality of strip-shaped electrodes formed parallel to each other on a substrate, to be moved together with the substrate in relation to each other to thereby perform rubbing treatment on the surface of the film-to-be-treated,wherein the rotation axis of the rubbing roller is parallel to the surface of the film-to-be-treated during the rubbing treatment,wherein an angle .theta.3 in a plane parallel to the surface of the film-to-be-treated is formed by one of the implanting directions of the pile yarns of the rubbing roller and the longitudinal direction of the strip-shaped electrodes of the substrate and is selected to be in a range of from +5 degrees to -5 degrees,wherein an angle .theta.5 formed by the direction of a rotation axis of the rubbing roller and one of the implanting directions of the pile yarns is selected to be in a range between 10 and 60 degrees.
