METHOD FOR MANUFACTURING OPTICAL LAYERED BODY, AND ELLIPTICALLY POLARIZING PLATE, CIRCULARLY POLARIZING PLATE COMPRISING THE LAYERED BODY AND LIQUID CRYSTAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for layering an optical element comprising a liquid crystal substance layer having no supporting substrate film.

SOLUTION: The optical layered body is manufactured in the following processes. They are: a first process of adhering a liquid crystal substance layer 1 having alignment of the liquid crystal fixed and being formed on an alignment substrate to a removable substrate 1 via an adhesive layer 1, and then stripping the alignment substrate to transfer the liquid crystal substance layer 1 onto the removable substrate 1 to obtain a layered body (A) consisting of the removable substrate 1/adhesive layer 1/liquid crystal substance layer 1; a second process of laminating a liquid crystal substance layer 2 having alignment of the liquid crystal fixed and being formed on an alignment substrate to the above liquid crystal substance layer 1 via a tacky adhesive (adhesive) layer to obtain a layered body consisting of the removable substrate 1/adhesive layer 1/liquid crystal substance layer 1/tacky adhesive (adhesive) layer/liquid crystal substance layer 2/alignment substrate; and a third process of stripping the removable substrate 1 and the alignment substrate of the above layered body and laminating a polarizing plate on the adhesive layer 1 or the liquid crystal substance layer 2.
