Title:
INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/003732
Kind Code:
A1
Abstract:
An input device according to an embodiment of the present invention is provided with a sensor unit, an optical layer stacked on the sensor unit, and a flexible wiring substrate having a connection region that is sandwiched between the optical layer and a support base material. The flexible wiring substrate has a flexible base material provided with an electrode layer, and a wiring end section that is an end section of the electrode layer and that is conductively connected to a terminal unit by an electroconductive junction member. The position of the wiring end section is further back than the position of the end of the flexible base material, and thus, a projecting portion that projects toward a detection region is formed on the flexible base material. The input device has a portion where the electroconductive junction member does not protrude further towards the detection region side than the tip of the projecting portion, and thus, it is possible to reduce the region where bubbles are formed between the sensor unit and the optical layer.
