Abstract

Official abstract text for this publication.

A touch panel module in which a conductive film in which a mesh conductive layer composed of a mesh-like metal electrode is formed on a support, a λ/4 plate, a polarizing plate, and a protective layer are arranged in this order. A λ/4 plate is further arranged on a side of the conductive film opposite to the protective layer. The touch panel module has a visible light diffuse reflectivity of 2% or less, which is measured from the protective layer.

First claim
