Abstract: An optical film roll is disclosed capable of realizing excellent display characteristics while maintaining manufacturing efficiency. The optical film roll has a width corresponding to a pair of opposite sides of a liquid crystal cell and is used by being cut to a length corresponding to another pair of opposite sides of the liquid crystal cell to be continuously attached to a surface of the liquid crystal cell. The optical film roll includes a long optical film wound into a roll shape, the long optical film being obtained by subjecting a long optical raw film, which includes a polarizing film having an absorption axis in its width direction, to a slitting process in a machine direction while conveying the long optical raw film in its lengthwise direction. The polarizing film includes a polyvinyl alcohol-based resin film that contains a dichromatic substance and has an Nz coefficient of 1.10 or more.

Abstract: A method is disclosed including causing a preform 1 that is softened to pass from an inner side of a container-shaped member 10 having a shape of a container having a through hole 12 at a bottom thereof through the through hole 12. The preform 1 includes a resin. At least an inner surface 10i of the container-shaped member 10 is formed of a material including glass, a heat-resistant resin, or aluminum as a main component. In one embodiment of the present invention, the preform 1 is heated while the preform 1 and a metallic member 20 in which the container-shaped member 10 is disposed are not in direct contact with each other, and the preform 1 softened thereby is caused to pass through the through hole 12 and then through a tubular portion 26 of the metallic member 20 to shape the preform 1 into a fibrous shape.
