CAPACITIVE TOUCH SENSOR LAMINATE FOR DISPLAY PANEL DEVICE

摘要

Provided is a configuration capable of suppressing the visibility of an electrode pattern, and preventing curvature deformation caused by changes in temperature or humidity conditions in a capacitive touch sensor laminate having a touch-input function. A capacitive touch sensor laminate for use in a display panel device having a touch-input function is provided with: a dielectric center substrate structure having flat surfaces formed from a transparent resin material on both sides thereof; one or more transparent coat layers formed on each of the flat surfaces; and a transparent conductive layer formed on and adjacent to the coat layers. The one or more coat layers include at least one refractive index modulation layer for suppressing the visibility of the pattern of an electrode formed from the transparent conductive layer. The thickness of the coat layers formed on each of the flat surfaces is set in a manner such that the layers sandwiching the dielectric center substrate structure on both sides thereof are symmetrical to one another.
