Abstract:
1. A method for manufacturing an optical display, comprising the steps of: feeding a belt and sheet-shaped product comprising at least (i) an optical film as a component of the optical display, (ii) a pressure-sensitive adhesive for sticking to the optical display unit and (iii) a release film for protecting the pressure-sensitive adhesive from a roll of the belt and sheet-shaped product; detecting a defect of the belt and sheet-shaped product supplied by the feeding step; thoroughly cutting all layers of the belt and sheet-shaped product into individual sheet-shaped products based on a result of the detection in the detecting step so as to separate the individual sheet-shaped products having no defect from the individual sheet-shaped products having a defect; transferring each of the sheet-shaped products having no defect from the cutting step; and sticking the sheet-shaped product transported by the transferring step to an optical display unit as another component of the optical display with the pressure-sensitive adhesive interposed therebetween, wherein all of the steps are performed on a continuous manufacturing line.
