Title:
INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/104810
Kind Code:
A1
Abstract:
Provided is an input device capable of suppressing unintended visibility of a pattern formed on a substrate. The device is provided with a position-detecting part that is provided on a substrate and comprises a plurality of detection electrodes, an optical layer provided above the position-detecting part, an optically transparent adhesive layer provided above the optical layer, and a protective member provided above the optically transparent adhesive layer. The plurality of detection electrodes comprises a first electrode and a second electrode that extend in intersecting directions, a bridge wire provided at the intersection of the first electrode and the second electrode, and an insulating layer provided between the substrate and the bridge wire. In the present input device, the refractive index of the optical layer is greater than the refractive index of the insulating layer, and less than the refractive indexes of the first and second electrodes.
