摘要： PROBLEM TO BE SOLVED: To provide a process for producing an optical display unit which eliminates the problem that when a sheet product having a property of curving is half-cut in preparation for laminating the sheet product to a substrate through a pressure-sensitive adhesive while peeling a uncut member, the cut sheet product curls during conveyance after the half cutting and which enables the sheet product to be satisfactorily laminated to the substrate. SOLUTION: The process for producing the optical display unit comprises the steps of: unwinding a roll of a continuous sheet product comprising an optical member and a release film disposed on one surface of the member through a pressure-sensitive adhesive; cutting the sheet product with a cutter while leaving the release film uncut; and then laminating the sheet product to the substrate through the pressure-sensitive adhesive while removing the release film. This sheet product has such a constitution that when no external force is being exerted thereon, the sheet product curls in the lengthwise direction with the release film facing inward.
