Title:
METHOD FOR PRODUCING OPTICAL LAMINATE
Document Type and Number:
WIPO Patent Application WO/2017/126490
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for efficiently producing an optical laminate, said method preventing a decrease in quality of the optical laminate due to large bubbles being entrained on an affixing surface for a polarizer plate. A method for producing an optical laminate having at least a protection film, a first adhesive-agent layer, and a polarizer plate, wherein the method for producing an optical laminate includes: a step for affixing the protection film, the first adhesive-agent layer, and the polarizer plate and creating an precursor for an optical laminate; and a step for placing the precursor for an optical laminate in an atmosphere of 0.2 MPaG or greater and a temperature lower than 50°C.
