Display device with touch panel
View Patent ↗A touch panel includes a substrate having a plurality of first electrodes extending in a first direction on the substrate, and a plurality of second electrodes three-dimensionally intersecting the plurality of first electrodes. Each of the plurality of first electrodes includes a first portion formed on a layer different from a layer of the plurality of second electrodes to three-dimensionally intersect one of the plurality of second electrodes, and a second portion formed on the same layer as the layer of the plurality of second electrodes to be separated from the plurality of second electrodes. An insulating film made of negative resist is formed between the first portion and the second portion, and the first portion is electrically connected to the second portion via a contact portion formed through the insulating film.
1. A touch panel comprising:
a substrate, a plurality of first electrodes extending in a first direction on the substrate and being disposed in parallel in a second direction intersecting the first direction, and a plurality of second electrodes intersecting the plurality of first electrodes, extending in the second direction, and being disposed in parallel in the first direction;
wherein each of the plurality of first electrodes includes a first portion formed in a layer different from a layer of the plurality of second electrodes to intersect one of the plurality of second electrodes, and a second portion formed in the same layer as the layer of the plurality of second electrodes to be separated from the plurality of second electrodes;
wherein an insulating film made of negative resist is formed between the first portion and the second portion; and
wherein the first portion is electrically connected to the second portion via a contact portion formed on the insulating film.
2. A touch panel according to claim 1 , wherein the first portion is formed above the plurality of second electrodes.
3. A touch panel according to claim 1 , wherein the first portion is formed below the plurality of second electrodes.
4. A touch panel according to claim 1 , wherein: each of the plurality of second electrodes includes a portion wider than a portion intersecting the first portion, between adjacent two electrodes of the plurality of first electrodes; and
each of the plurality of first electrodes includes the second portion to be larger in width than the first portion, between adjacent two electrodes of the plurality of second electrodes.
5. A touch panel according to claim 1 , wherein the plurality of first electrodes and the plurality of second electrodes are made of transparent conductive materials.
6. A touch panel according to claim 1 , further comprising a protective film formed on the substrate to cover the plurality of first electrodes and the plurality of second electrodes.
7. A capacitance coupling type touch panel comprising:
a substrate, a plurality of first electrodes extending in a first direction on the substrate and being disposed in parallel in a second direction intersecting the first direction, and a plurality of second electrodes intersecting the plurality of first electrodes, extending in the second direction, and being disposed in parallel in the first direction;
wherein each of the plurality of first electrodes includes a first portion formed in a layer different from a layer of the plurality of second electrodes to intersect one of the plurality of second electrodes, and a second portion formed in the same layer as the layer of the plurality of second electrodes to be separated from the plurality of second electrodes;
wherein an insulating film made of negative resist is formed between the first portion and the second portion; and
wherein the first portion is electrically connected to the second portion via a contact portion formed on the insulating film.
