TOUCH PANEL
A touch panel includes a light-permeable substrate, an insulating layer disposed on a lower surface of the substrate, first light-permeable electrodes having substantially strip shapes disposed on a lower surface of the insulating layer, and second light-permeable electrodes having substantially strip shapes disposed on the lower surface of the insulating layer. Each of the first electrodes includes electrode segments having substantially rectangular shapes and connection segments for connecting the first electrode segments. The touch panel has a small number of parts, is inexpensive, and is reliably operated.
1 . A touch panel comprising:
a substrate that is light-permeable;
an insulating layer disposed on a lower surface of the substrate, the insulating layer being ultraviolet curable or electron-ray curable;
a plurality of first electrodes that are light-permeable and have substantially a strip shapes extending in a first lengthwise direction, the plurality of first electrodes being disposed on a lower surface of the insulating layer and arranged in a predetermined first arranging direction, each of the plurality of first electrodes including
a plurality of first electrode segments having substantially rectangular shapes arranged in the first lengthwise direction, and
a plurality of first connection segments for connecting the plurality of first electrode segments; and
a plurality of second electrodes that are light-permeable and have substantially strip shapes extending in a second lengthwise direction different from the first lengthwise direction, the second electrodes being disposed on the lower surface of the insulating layer to be spaced apart by a predetermined gap from the plurality of first electrodes, the second electrodes being arranged in a second arranging direction different from the first arranging direction.
2 . The touch panel according to claim 1 ,
wherein the insulating layer has a plurality of insulating sections disposed between each of the plurality of first electrodes and respective one of the plurality of second electrodes,
wherein the plurality of first electrode segments are disposed on the lower surface of the insulating layer, and
wherein the plurality of first connection segments are positioned above the plurality of second electrodes such that each of the plurality of first electrode segments faces respective one of the second electrodes via respective one of the plurality of insulating sections.
3 . The touch panel according to claim 2 , wherein the plurality of first connection segments are embedded in the insulating layer so as not to be exposed to an outside the insulating layer.
4 . The touch panel according to claim 2 ,
wherein each of the plurality of second electrodes includes:
a plurality of second electrode segments having substantially rectangular shapes disposed on the lower surface of the insulating layer and arranged in the second lengthwise direction; and
a plurality of second connection segments disposed on the lower surface of the insulating layer so as to connect the plurality of the second electrode segments, and
wherein the plurality of first connection segments are positioned above the plurality of second connection segments such that each of the plurality of first connection segment faces respective one of the plurality of second connection segments via respective one of the plurality of insulating sections of the insulating layer.
