Capacitive touch sensor laminate for display panel device

A capacitive touch sensor laminate for use in a display panel device having a touch input function, comprising:

• a dielectric central substrate structure made of a transparent resin material and formed to have flat surfaces, respectively, on opposite sides thereof;
• an at least one-layer structured coat layer made of a transparent material and formed on each of the flat surfaces;
• and
• a transparent electrically conductive layer formed on and in adjacent relation to the coat layer;
• wherein;
• the at least one-layer structured coat layer comprises at least one refractive index adjusting layer for suppressing visibility of an electrode pattern formed by the transparent electrically conductive layer, and
• the at least one-layer structured coat layers formed on respective ones of the flat surfaces are configured such that thicknesses of corresponding layers therein on respective opposite sides of the dielectric central substrate structure are set to allow the corresponding layers to become mutually symmetrical across the dielectric central substrate structure.
