Abstract

A flexible touch panel having a bending region which is bendable and a flat region, includes: a plurality of first unit conductive patterns formed in the flat region; and a plurality of second unit conductive patterns formed in the bending region, and the second unit conductive pattern has a smaller width than the first unit conductive pattern.

First claim

What is claimed is:

1 . A flexible touch panel having a bending region which is bendable and a flat region, comprising:
a plurality of first unit conductive patterns formed in the flat region; and a plurality of second unit conductive patterns formed in the bending region, wherein the second unit conductive pattern has a smaller width than the first unit conductive pattern.

2 . The flexible touch panel of claim 1 , wherein the bending region is bended to have a radius of curvature R.

3 . The flexible touch panel of claim 2 , wherein the second unit conductive pattern has a width of πR/10 to πR/2.

4 . The flexible touch panel of claim 1 , wherein the plurality of second unit conductive patterns comprises a plurality of first sub-patterns arranged in a first direction, and a plurality of second sub-patterns arranged in a second direction.

5 . The flexible touch panel of claim 4 , further comprising:
a third sub-pattern arranged in the first direction between the second sub-patterns.

6 . The flexible touch panel of claim 5 , wherein the third sub-pattern is connected to an adjacent second sub-pattern.

7 . The flexible touch panel of claim 5 , wherein the third sub-pattern acts as a dummy electrode.

8 . The flexible touch panel of claim 1 , wherein the first unit conductive pattern comprises a plurality of divided patterns divided to have a size corresponding to the second unit conductive pattern.

9 . The flexible touch panel of claim 8 , wherein each of the divided patterns are electrically connected to adjacent divided patterns by a connection portion.

10 . The flexible touch panel of claim 9 , wherein the connection portion is formed to have a plurality of portions between adjacent divided patterns.

11 . The flexible touch panel of claim 8 , wherein the plurality of divided patterns and the connection portion are integrally formed.

12 . The flexible touch panel of claim 1 , further comprising:
an auxiliary electrode formed on the first unit conductive pattern.

13 . The flexible touch panel of claim 1 , further comprising:
an auxiliary electrode formed on the second unit conductive pattern.
