METHOD FOR MANUFACTURING ORIENTED FILM, ORIENTED FILM, POLARIZING PLATE, AND LIQUID CRYSTAL DISPLAYING APPARATUS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an oriented film having a small fluctuation in the angle of orientation and the film thickness over the whole width.

SOLUTION: In the method for manufacturing the oriented film in which the oriented film is manufactured by delivering a thermoplastic resin film from a direction inclined by an angle of θ (0°<θ<50°) to the winding direction of the film after orientation while both side ends in the width direction of the thermoplastic resin film are gripped by using a plurality of gripping tools and the distances of the gripping tools are widened accompanied with movement in the longitudinal direction, when the space between the gripping tools before orientation is Is and the space between the gripping tools after orientation is Ie, an equation of 1.0COPYRIGHT: (C)2008,JPO&INPIT
