Title:
RESIN FILM, METHOD FOR MANUFACTURING RESIN FILM, POLARIZING PLATE, AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/113414
Kind Code:
A1
Abstract:
A long resin film is manufactured by elongating a film in the width direction so that the elongation rate of the film reaches 20-50%, forming band-like embossed portions in the conveyance direction at both ends of the film in the direction vertical to the conveyance direction, and then winding the film having the embossed portions in a roll shape, according to a solution casting film-forming method. The resin film is characterized in that the film thickness after the winding is 20-70 μm, the hygroscopic expansion coefficient in the drawing direction is 4 × 10-5-8 × 10-5 cm/cm·%RH, and the height of the emboss sections after the winding is 2-3.5 μm.
