Abstract

The present application relates to a conductive structure body and a method for manufacturing the same. A conductive structure body according to an exemplary embodiment of the present application comprises a substrate; a metal layer provided on the substrate; and a light reflection reducing layer provided on at least one surface of the metal layer and comprising copper-manganese-nickel oxide.

First claim

The invention claimed is:

1. A touch screen panel comprising a conductive structure body,
wherein the conductive structure body comprises:
a substrate;
a metal layer provided on the substrate; and
a light reflection reducing layer provided on at least one surface of the metal layer and consisting of copper-manganese-nickel oxide,
wherein the copper content is 28 to 46 at %, the manganese content is 3 to 12 at %, the nickel content is 17 to 24 at %, and the oxygen content is 18 to 52 at % in the light reflection reducing layer,
wherein a ratio of the oxygen content to the sum of the copper, manganese, nickel, and oxygen contents in the light reflection reducing layer is 0.18 to 0.52.

2. The touch screen panel of claim 1 , wherein in light having a wavelength range of 380 nm to 780 nm, an extinction coefficient k of the light reflection reducing layer is 0.6 or more and 1.4 or less.

3. The touch screen panel of claim 1 , wherein in light having a wavelength range of 380 nm to 780 nm, a refractive index n of the light reflection reducing layer is 1.7 or more and 2.8 or less.

4. The touch screen panel of claim 1 , wherein a total reflection of the conductive structure body is 40% or less.

5. The touch screen panel of claim 1 , wherein a thickness of the light reflection reducing layer is 0.1 to 400 nm.

6. The touch screen panel of claim 1 , wherein a thickness of the light reflection reducing layer is 0.1 to 100 nm.

7. The touch screen panel of claim 1 , wherein a thickness of the metal layer is 0.01 to 10 pm.

8. The touch screen panel of claim 1 , wherein the metal layer comprises one or two or more selected from the group consisting of Cu, Al, Ag, Nd, Mo, Ni and alloys thereof.

9. The touch screen panel of claim 1 , wherein the metal layer is a patterned metal pattern layer, and the light reflection reducing layer is a patterned light reflection reducing pattern layer.

10. The touch screen panel of claim 9 , wherein a line width of the metal pattern layer is 10 μm or less.

11. The touch screen panel of claim 9 , wherein a surface resistance of the conductive structure body is 1 Ω/sq to 300 Ω/sq.
