Title:
PRODUCTION METHOD FOR LAMINATED OPTICAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2015/030062
Kind Code:
A1
Abstract:
A production method for a laminated optical member formed by laminating an optical member on to an optical display component. The production method has: a laminated optical member formation step (S13) in which a belt-shaped optical member sheet is wound out from a starting material roll, the plurality of optical members obtained by cutting the optical member sheet are laminated on to a plurality of optical display components, and a plurality of laminated optical members are formed; a first autoclave processing step (S14) in which the plurality of laminated optical members are heated and pressurized; and a first visual inspection step (S21) in which, after the first autoclave processing step, a visual inspection for defects is made for each of the plurality of heated and pressurized laminated optical members. The laminated optical member formation step (S13) and the first autoclave processing step (S14) are both performed on the same production line and the first visual inspection step (S21) is performed separately from the production line.
