| 20100149470 | PRECURSOR FILM FOR RETARDATION FILMS, RETARDATION FILM, AND LIQUID CRYSTAL DISPLAY DEVICE - Provided is a film that is made of a propylene-based copolymer selected from among propylene-based random copolymers and propylene-based block copolymers, the film being useful as a precursor film for the production of a retardation film by stretching. The propylene-based copolymer forming the film contains crystals containing smectic crystals, wherein the percentage of smectic crystals to all the crystals of the propylene-based copolymer. The film has an in-plane retardation of 50 nm or less and a thickness falling within the range of 30 to 200 μm. The propylene-based copolymer is a copolymer that has a parameter (A) falling within the range of from 0.0007 to 0.1, the parameter (A) being calculated from Formula (1) defined for a stress-strain curve produced as a result of stretching a film made of the polymer at a tensile rate of 100 mm/minute at a temperature at which a stress of 0.8±0.1 MPa is produced at a strain of 200%: | 06-17-2010 |
| 20100222517 | OPTICAL FILM - An optical film having at least one layer formed of a polyolefin based resin composition containing 8 to 30 wt % of a component (A) defined below and 92 to 70 wt % of a component (B) defined below, with the proviso that the total of the component (A) and the component (B) is 100 wt %:
