A touch sensor includes a substrate layer, a plurality of sensing electrodes on the substrate layer, and at least one device hole penetrating through one or more of the sensing electrodes. A functional device of an image display device may overlap the device hole so that an optical interference by the touch sensor may be prevented.

Multi-touch touch-sensing devices and methods are described herein. The touch sensing devices can include multiple sense points, each located at a crossing of a drive line and a sense line. In some embodiments, multiple drive lines may be simultaneously or nearly simultaneously stimulated with drive signals having unique characteristics, such as phase or frequency. A sense signal can occur on each sense line that can be related to the drive signals by an amount of touch present at sense points corresponding to the stimulated drive lines and the sense line. By using processing techniques based on the unique drive signals, an amount of touch corresponding to each sense point can be extracted from the sense signal. The touch sensing methods and devices can be incorporated into interfaces for a variety of electronic devices such as a desktop, tablet, notebook, and handheld computers, personal digital assistants, media players, and mobile telephones.

A touch panel includes: an transparent substrate; an X wiring line; a Y wiring line; and an inter-layer insulating film which electrically separates the X wiring line and the Y wiring line at an intersection at which the X wiring line and the Y wiring line intersect in a plan view. At the intersection, the bottom layer of one wiring line of the X wiring line and the Y wiring line continues on the lower surface side of the inter-layer insulating film, and layers of the one wiring line except the bottom layer are divided. Further, at the intersection, layers of the other wiring line of the X wiring line and the Y wiring line except the top layer of the other wiring line are divided, and the top layer of the other wiring line continues on the upper surface side.
