Abstract

The present invention provides a touch panel and a method for manufacturing the touch panel. The touch panel is arranged on a display panel and adopts a capacitive method operated by touching an operation surface. On the back side of the operation surface, a plurality of X electrodes are formed along the X direction and a plurality of Y electrodes are formed along the Y direction perpendicular to the X direction. The plurality of X electrodes and the plurality of Y electrodes have: a plurality of transparent electrodes formed on the same surface of the back side; A jumper wire that three-dimensionally connects any one of the transparent electrodes of the adjacent X electrodes or the transparent electrodes of the adjacent Y electrodes. The jumper has a first layer connected to the transparent electrode and a second layer stacked on the first layer. The first layer includes a first metal oxide film, and the second layer includes a second metal oxide film. The first layer has a lower refractive index than the second layer.

Description

technical field

[0001] The present invention relates to a technique suitable for use in a touch panel formed integrally with a cover plate and a method for manufacturing the touch panel. Background technique

[0002] A touch panel is a component of an input device that enables data input by detecting a touched position by an operator touching a transparent surface on a display screen with a finger or a pen, and enables direct and intuitive input by keyboard input. Therefore, in recent years, it has been widely used in operation parts of various electronic devices, represented by mobile phones, portable information terminals, and car navigation systems.

[0003] The touch panel can be used as an input device by being attached to a display screen of a flat display device such as a liquid crystal panel. The detection methods of the touch panel include resistive, capacitive, ultrasonic, and optical, and have various structures.

[0004] The capacitive touch panel can be roughl...
