MANUFACTURING METHOD FOR LAMINATED RETARDATION PLATE, LAMINATED RETARDATION PLATE OBTAINED BY SAME, AND OPTICAL FILM AND IMAGE DISPLAY DEVICE USING SAME

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for a laminated retardation plate in which the adhesion between a transparent base material and a retardation layer can be improved without influencing the performance of the retardation layer.;SOLUTION: In the manufacturing method for the laminated retardation plate wherein the retardation layer is formed by forming a polymerizable liquid crystal compound layer on a surface of a transparent base material with alignment restricting power, aligning the polymerizable liquid crystal compound with the alignment restricting power, and fixing the alignment by polymerizing the polymerizable liquid crystal compound either in or after the alignment, a surface property modifying layer is further formed on the surface of the base material by using a forming material of the surface property modifying layer containing a silane coupling agent, the polymerizable liquid crystal compound layer is formed across it, and a polymerization initiator is interposed at least either in the surface property modifying layer or on the interface between the surface property modifying layer and polymerizable liquid crystal compound layer to carry out the polymerization. Here, the polymerization initiator may be mixed with the polymerizable liquid crystal compound layer.;COPYRIGHT: (C)2006,JPO&NCIPI
