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.
