Abstract

Provided is a conductive pattern having at least one unit conductive pattern forming one touch pixel according to an aspect of the present invention. The at least one unit conductive pattern includes a plurality of nanostructures each having opposite ends. A ratio of nanostructures, both opposite ends of which are in contact with edges of the at least one unit conductive pattern to all nanostructures included in the at least one unit conductive pattern is 70% or more.

First claim

1 . A conductive pattern including at least one unit conductive pattern comprising a touch pixel, the unit conductive pattern comprises:
a plurality of nano structures having both ends, wherein a ratio of the nano structure in which both ends are in contact with side surfaces of the unit conductive pattern is 70% or more of a total nano structure.

2 . The conductive pattern of claim 1 , further comprises:
a connection portion connecting adjacent unit conductive patterns, wherein a ratio of the nano structure in which both ends are in contact with side surfaces of the connection portion of a total nano structure of the connection portion is different from the ratio of the nano structure in which both ends are in contact with side surfaces of the unit conductive pattern.

3 . The conductive pattern of claim 2 , wherein the ratio of the nano structure in which both ends are in contact with side surfaces of the connection portion of a total nano structure of the connection portion is 80% or more.

4 . The conductive pattern of claim 2 , wherein a width of the connection portion is 50% to 60% of a width of the unit conductive pattern.

5 . The conductive pattern of claim 1 , wherein the nano structure comprises a silver (Ag) material.

6 . The conductive pattern of claim 1 , wherein the nano structure is formed by electro-spinning.

7 . The conductive pattern of claim 1 further comprises a matrix containing the plurality of the nano structures.

8 . The conductive pattern of claim 7 , wherein an end of the nano structure in contact with a side surface of the unit conductive pattern is exposed to an outside of the matrix.

9 . The conductive pattern of claim 7 , wherein the matrix includes a conductive material.

10 . The conductive pattern of claim 7 , wherein the matrix prevents oxidation of the plurality of nano structures.

11 . The conductive pattern of claim 1 , wherein the nano structure in which both ends are in contact with side surfaces of the unit conductive pattern intersects at least point with a straight line connecting the both ends.
