MULTILAYER STRUCTURE AND TOUCH PANEL MODULE

摘要

A multilayer structure has a laminate including a transparent conductive member having a conductive pattern having a mesh structure composed of thin metal wires on a transparent substrate having flexibility, a protective member for protecting the transparent conductive member, and an optically transparent adhesive layer disposed between the transparent conductive member and the protective member. The thickness of the laminate is 100 μm or more and 600 μm or less. The thickness of the adhesive layer is 20% or more of the thickness of the laminate. The thermal shrinkage of the transparent conductive member at 150° C. is 0.5% or less, and a difference between the thermal shrinkage of the transparent conductive member and the thermal shrinkage of the protective member at 150° C. is within 60% of the thermal shrinkage of the transparent conductive member at 150° C. The multilayer structure is used for a touch panel module having a three-dimensional shape.
