Abstract

Disclosed herein is a touch panel. The touch panel includes a transparent substrate and a plurality of transparent electrodes. The transparent electrodes are formed on one surface of the transparent substrate. Each of the transparent electrodes includes a touch part formed to have an identical width and a connection part configured in a stepped form along with the touch part and configured to connect the touch part with the transparent substrate.

Claims

1. A touch panel, comprising:

a transparent substrate; and

a plurality of transparent electrodes formed on one surface of the transparent substrate, each of the transparent electrodes comprising;

a touch part formed to have an identical width; and

a connection part configured in a stepped form along with the touch part, and configured to connect the touch part with the transparent substrate.

2. The touch panel as set forth in claim 1, wherein the transparent electrodes are formed to have different capacitance values.

3. The touch panel as set forth in claim 1, wherein the touch parts are formed to have an identical thickness.

4. The touch panel as set forth in claim 1, wherein the touch parts are formed to have different thicknesses.

5. The touch panel as set forth in claim 1, wherein the connection parts are formed to have different widths.

6. The touch panel as set forth in claim 1, wherein the connection parts are formed to have an identical thickness.

7. The touch panel as set forth in claim 1, wherein the connection parts are formed to have different thicknesses.

8. The touch panel as set forth in claim 1, wherein the touch part and the connection part are configured to have a T-shaped section.

9. The touch panel as set forth in claim 1, further comprising:

a first wiring configured to connect ones of the transparent electrodes, arranged in each odd column or row, to each other; and

a second wiring configured to connect ones of the transparent electrodes, arranged in each even column or row, to each other.

10. The touch panel as set forth in claim 9, wherein the first wiring and the second wiring are disposed across spaces formed by the stepped form in which the touch part and the connection part are configured.

11. The touch panel as set forth in claim 9, wherein the first wiring and the second wiring are disposed between the transparent electrodes.
