Abstract

A touch panel includes an operation surface, a plurality of light-transmitting belt-like first conductive layers, belt-like second conductive layers, low-reflective layers, and a substrate. Each of the second conductive layers includes conductive parts and connecting parts. The conductive parts are formed between the plurality of first conductive layers. Each of the connecting parts is insulated from the first conductive layers, crosses over the first conductive layers, and electrically connects adjacent conductive parts. The low-reflective layers are formed between the connecting parts and the operation surface. The substrate supports the first conductive layers, the second conductive layers and the low-reflective layers. The surfaces of the low-reflective layers have lower light reflectivity than that of the surfaces of the connecting parts.

Claims (34)
