A touch sensor has a base layer and an electrode layer. The electrode layer includes a first transparent oxide layer formed on the base layer, a conductive metal layer formed on the first transparent oxide layer, and a second transparent oxide layer formed on the conductive metal layer and has a plurality of through-holes with the same shape and spacing.

Touch sensor and laminate including the same

A touch sensor includes a sensing part in which a plurality of sensing cells is arranged and connected and a wiring part connected to the sensing part and formed outside the sensing part. The wiring part includes a first divisional wiring part having a plurality of first divisional wires having a connecting protrusion with a width larger than that of the wiring at one end thereof and a second divisional wiring part having a plurality of second divisional wires having one end thereof with a width smaller than that of the connecting protrusion and coupled to and overlapped with the connecting protrusion. The first divisional wiring part and the second divisional wiring part are formed by divisional exposure.

Touch sensor having wiring overlapping part

A touch sensor includes a substrate and first and second touch sensor electrode layers. The first touch sensor electrode layer is disposed on a first surface of the substrate, and includes a first pad formed on an opposing surface to a surface in contact with the substrate. The second touch sensor electrode layer is disposed on a second surface of the substrate, exposes at least a portion of the surface in contact with the substrate to an outside of the substrate, and includes a second pad formed on the portion exposed to the outside of the surface in contact with the substrate. The first pad and the second pad do not overlap in a stacking direction.

Touch sensor

A touch sensor includes: a display portion including a base layer and a touch sensor layer on the base layer; a bending portion extending from the display portion and including a first part of a trace electrically connected to the touch sensor layer but not including the base layer; and a bonding portion extending from the bending portion and including a second part of the trace, wherein an end portion of the second part of the trace is connected to a flexible circuit board.
