<p>The present invention relates to a rubbing treatment method and manufacturing method of an optical film which can reduce reduction of foreign-matter-adhesion failures, and orientation defect failures, and a manufacturing method of an optical film. From the rear side of a sheet (W) and a friction roller (72) of the contact surface, from a pneumatic press means (50) of a nozzle (50A) of the discharge pressure of the air over the entire width of the sheet toward the support body (W) is applied, whereby the sheet (W) to the friction roller (72) in the pressing step, the central portion has an aperture ratio higher than the opening pressure of both end portions of the sheet (W) disposed in the width direction using loss plate (52) of a pneumatic press means (50) to a rubbing treatment.</p> |
