Abstract

A touch panel includes a cover substrate; a first sensing electrode including first unit sensing electrodes spaced apart from each other in a first direction on the cover substrate and first connecting electrodes to connect the first unit sensing electrodes to each other; a second sensing electrode including second unit sensing electrodes spaced apart from each other in a second direction on the cover substrate; and a bridge electrode insulated from the first unit sensing electrodes to connect the second unit sensing electrodes to each other, wherein the bridge electrode includes connecting bridge electrodes to connect the second unit sensing electrodes to each other and second unit bridge electrodes overlapping with the second unit sensing electrodes.

Claims (28)

1. A touch panel comprising:

a cover substrate;

a first sensing electrode including first unit sensing electrodes spaced apart from each other in a first direction on the cover substrate and first connecting electrodes to connect the first unit sensing electrodes to each other;

a second sensing electrode including second unit sensing electrodes spaced apart from each other in a second direction on the cover substrate;

a bridge electrode insulated from the first unit sensing electrodes to connect the second unit sensing electrodes to each other; and

an insulating layer on at least one of the first sensing electrode and the second sensing electrode;

wherein the bridge electrode includes connecting bridge electrodes to connect the second unit sensing electrodes to each other and second unit bridge electrodes overlapping with the second unit sensing electrodes;

wherein the first unit sensing electrode, the second unit sensing electrode, and the first connecting electrode are formed directly on one surface of the cover substrate;

wherein the bridge electrode is provided on at least a part of upper portions of the first connecting electrode, the first unit sensing electrode, and the second unit sensing electrode to make direct contact with the second unit sensing electrode;

wherein a through-hole is formed in the insulating layer; and

wherein the bridge electrode is disposed on the insulating layer and connects the second unit sensing electrodes to each other through the through-hole, and the bridge electrode entirely overlaps with at least one of the first sensing electrode and the second sensing electrode.

2. The touch panel of claim 1 , wherein the first and second sensing electrodes are provided on a same surface of the cover substrate.

3. The touch panel of claim 1 , wherein the bridge electrode further includes a first unit bridge electrode overlapping with the first unit sensing electrode.

4. The touch panel of claim 3 , wherein the through-hole includes a first through-hole and a second through-hole,

the second unit sensing electrode is connected to the connecting bridge electrode or the second unit bridge electrode through the first through-hole; and

the first unit sensing electrode is connected to the first unit bridge electrode through the second through-hole.

5. The touch panel of claim 4 , wherein the insulating layer is disposed on the connecting bridge electrode.

6. The touch panel of claim 4 , wherein the insulating layer overlaps with the bridge electrode.

7. The touch panel of claim 4 , wherein the first and second sensing electrodes and the bridge electrode include a same material.

8. The touch panel of claim 1 , wherein the insulating layer is disposed on a front surface of the first and second sensing electrodes.

9. The touch panel of claim 1 , wherein the insulating layer has a shape equal to a shape of the first or second sensing electrode.
