Patent ID: 8823653

Claim:
A capacitive input device comprising: a translucent substrate having an input region; first translucent electrode lines, arranged in the input region, extending in a first direction; second translucent electrode lines, arranged in the input region, extending in a second direction intersecting with the first direction; interlayer insulating layers composed of acrylic resins and having a thickness ranging from about 1-2 μm; and relay electrodes composed of ITO and having a thickness ranging from about 10-15 nm; wherein the first and second translucent electrode lines are disposed on a surface of the translucent substrate, the first translucent electrode lines intersect with the second translucent electrode lines at intersecting portions, portions of one of each first translucent electrode line and each second translucent electrode line are connected to each other with the intersecting portions, portions of the other are separated from each other with the intersecting portions, the interlayer insulating layers overlie the first or second translucent electrode line portions connected to each other with the intersecting portions, and the relay electrodes overlie the interlayer insulating layers to electrically connect the first or second translucent electrode line portions, separated from each other with the intersecting portions, to each other, wherein the first and second translucent electrode lines are configured to have refractive indices and thicknesses such that a first area of the input region that is covered by the first and second translucent electrode lines has at least substantially the same reflectivity as a second area of the input region that is not covered by the first and second translucent electrode lines, wherein the first and second translucent electrode lines are formed from a multilayer film including thin-films having different refractive indexes, wherein one of the translucent thin-films is a translucent conductive metal oxide layer and another one thereof is a translucent silicon compound layer, and wherein the translucent substrate is made of glass and the multilayer film includes a first ITO layer with a thickness of about 10 to 20 nm, a silicon dioxide layer with a thickness of about 40 to 60 nm, and a second ITO layer with a thickness of about 10 to 20 nm, these layers being arranged in that order.
