PROCESS FOR PRODUCING OPTICAL COMPENSATION FILM, OPTICAL COMPENSATION FILM, POLARIZING PLATE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A method for manufacturing an optical compensation film, the optical compensation film, a polarizing plate and liquid crystal display device are provided to suppress the oscillation effectively by making the crystallinity of an alignment layer positioned within a range from 0.2 to 0.8 and making the rubbing work positioned within a range from 300 to 800Nm per square meter. The band-shaped flexible supporting body(1a) is transmitted from a sender(2) from a roll(1) on which a film is mounted. The supporting body is guided by a guide roller(3) to a damper(4). The damper removes the dust adhered on one surface of the supporting body. A coater(5) coats the coating solution, including the composition for forming the alignment layer, on the supporting body. The supporting body where the coating film is formed is conveyed into a dryer(6), and then is guided into a rubbing treatment apparatus(8) by a guide roller(7).
