Abstract
A method for manufacturing an optical display unit including a substrate and an optical member having a polarizer, the optical member being bonded to the substrate with an adhesive interposed therebetween. The method includes a cutting step of feeding a continuous sheet material from a roll of the continuous sheet material, the continuous sheet material including the optical member and a release film provided on one side of the optical member with the adhesive interposed therebetween, and cutting the continuous sheet material by cutting means, while leaving the release film uncut, and a bonding step including bonding the sheet material to the substrate with the adhesive interposed therebetween, while removing the release film. When no external force is applied to the sheet material, the sheet material curls in the longitudinal direction so that the release film is facing inward.
