Abstract

Provided is a metal structure body comprising a substrate, a metal layer, and a color adjustment layer, where various colors are implemented by adjusting a thickness of the color adjustment layer, and a method for manufacturing the same. The metal structure body can implement various colors while having a small thickness, and has an effect that resistance characteristics of a metal layer do not deteriorate. The metal structure body can be applied to a bezel of a display board, to a touch screen panel and a display device.

First claim

The invention claimed is:

1. A bezel having a decorative color and a metal structure body for holding a display board, comprising:
a substrate;
a metal layer comprising aluminum and having a thickness from 1 nm to 10 μm; and
a color adjustment layer comprising oxynitrides of aluminum and having a thickness of 500 nm or less and an extinction coefficient in the range of 0.2 to 2.5,
wherein the metal layer is a patterned metal layer, and the color adjustment layer is a patterned color adjustment layer, and
wherein various colors are implemented by adjusting a thickness of the color adjustment layer.

2. The bezel of claim 1 , wherein the color adjustment layer is provided on at least one surface of the metal layer.

3. The bezel of claim 1 , wherein the metal layer is provided between the substrate and the color adjustment layer.

4. The bezel of claim 1 , wherein the color adjustment layer is provided between the substrate and the metal layer.

5. The bezel of claim 1 , wherein the metal layer further comprises one or an alloy of two or more selected from the group consisting of Al, Cu, Ni, V, W, Ta, Mo, Nb, Ti, Fe, Cr, Co, Au, and Ag.

6. The bezel of claim 1 , wherein the color adjustment layer further comprises one or two or more selected from the group consisting of oxides of a metal, nitrides of a metal, and carbides of a metal.

7. The bezel of claim 6 , wherein the metal is one or an alloy of two or more selected from the group consisting of Al, Cu, Ni, V, W, Ta, Mo, Nb, Ti, Fe, Cr, Co, Au, and Ag.

8. The bezel of claim 1 , wherein the metal layer further comprises copper, and the color adjustment layer further comprises oxides of copper.

9. A touch screen panel comprising the bezel of claim 1 .

10. A display device comprising the bezel of claim 1 .

11. The bezel of claim 1 , wherein the color adjustment layer further comprises one or two or more oxynitrides of a metal selected from the group consisting of Cu, Ni, V, W, Ta, Mo, Nb, Ti, Fe, Cr, Co, Au, and Ag.

12. The bezel of claim 1 , wherein the color adjustment layer further comprises one or two or more oxynitrides of a metal that is an alloy of two or more selected from the group consisting of Al, Cu, Ni, V, W, Ta, Mo, Nb, Ti, Fe, Cr, Co, Au, and Ag.

13. A method for manufacturing a bezel having a decorative color and a metal structure body for holding a display board, the method comprising:
forming a metal layer comprising aluminum having a thickness of 1 nm to 10 μm on a substrate; and
forming a color adjustment layer on the metal layer, the color adjustment layer having a thickness of 500 nm or less and an extinction coefficient in the range of 0.2 to 2.5 and comprising oxynitrides of aluminum,
wherein the metal layer is a patterned metal layer, and the color adjustment layer is a patterned color adjustment layer, and
wherein various colors are implemented by adjusting a thickness of the color adjustment layer.

14. The method of claim 13 , wherein the color adjustment layer has a thickness of 500 nm or less.

15. The method of claim 13 , wherein the forming of the metal layer uses a sputtering method, and the forming of the color adjustment layer uses a reactive sputtering method.

16. A method for manufacturing a bezel having a decorative color and a metal structure body for holding a display board, the method comprising:
forming a color adjustment layer on a substrate, the color adjustment layer having a thickness of 500 nm or less and an extinction coefficient in the range of 0.2 to 2.5 and comprising oxynitrides of aluminum; and
forming a metal layer comprising aluminum and having a thickness from 20 nm to 10 μm on the color adjustment layer,
wherein the metal layer is a patterned metal layer, and the color adjustment layer is a patterned color adjustment layer, and
wherein various colors are implemented by adjusting a thickness of the color adjustment layer.
