A method for manufacturing an optical display unit comprising a step for feeding a continuous sheet material from a roll of the continuous sheet material, wherein the continuous sheet material comprises the optical member and a release film provided on one side of the optical member with the adhesive interposed therebetween, and cutting the sheet material by cutting means, while leaving the release film uncut and bonding the sheet material to the substrate with the adhesive interposed therebetween, while removing the release film. When no external force is applied, the sheet material curls in the longitudinal direction in such a way that the release film is facing inward.
