摘要: Disclosed is a material roll that includes a roll of an optical film having defect information markings printed thereon and is resistant to the formation of a defect by the transfer of a bump/dent deformation at the marking site. The material roll includes a long sheet of an optical film with polarizer wound into roll shape; and marking(s) formed at or in a vicinity of at least one defect site. The marking has an optical density of 1.5 or more, and a thickness of a center part of the marking is 1.5 µm or less. The marking preferably has an optical density per unit thickness of 2.5 µm -1 or more.
