Optical laminate for front of in-cell touch panel liquid crystal element, in-cell touch panel liquid crystal display device, and method of manufacturing them

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical laminate for a front surface of an in-cell touch panel liquid crystal element capable of preventing white turbidity of a liquid crystal screen.SOLUTION: There is provided a manufacturing method of an optical laminate for a front surface of an in-cell touch panel liquid crystal element including the following steps of (a) to (c): (a) a step of laminating optical laminate forming members including a retardation plate and a polarizing film to form an optical laminate; (b) a step of forming a conductive layer on at least one member of the optical laminate forming members; and (c) a step of, while exposing a surface of the conductive layer, performing earth processing on the surface of the conductive layer.SELECTED DRAWING: None
