Abstract

A touch screen panel includes a window substrate divided into an active area and a non-active area, the non-active area being outside the active area, the window substrate having a first printed layer formed in the non-active area, a touch substrate including sensing electrodes formed in the active area and having a second printed layer that faces the first printed layer formed in the non-active area, and an adhesive layer interposed between the window substrate and the touch substrate.

First claim

What is claimed is:

1. A touch screen panel, comprising:
a window substrate divided into an active area and a non-active area, the non-active area being outside the active area, the window substrate having a first printed layer formed in the non-active area;
a touch substrate including sensing electrodes formed in the active area and having a second printed layer that faces the first printed layer formed in the non-active area; and
an adhesive layer interposed between the window substrate and the touch substrate, wherein at least a portion of the adhesive layer is interposed between the first printed layer and the second printed layer in a thickness direction of the touch screen panel,
wherein one surface of the adhesive layer covers a first surface of the first printed layer and another surface of the adhesive layer covers a first surface of the second printed layer, the first surface of the first printed layer facing the first surface of the second printed layer with the adhesive layer interposed therebetween, the first printed layer, the adhesive layer, and the second printed layer being stacked in the stated order in the thickness direction of the touch screen panel, and
wherein the thickness direction of the touch screen panel is a direction orthogonal to a plane of a surface of the touch substrate such that a line extending in the thickness direction separately passes through the first printed layer, the adhesive layer, and the second printed layer in the stated order.

2. The touch screen panel as claimed in claim 1 , wherein at least one of the first and second printed layers has a multi-layer structure.

3. The touch screen panel as claimed in claim 1 , wherein the first and second printed layers have different colors.

4. The touch screen panel as claimed in claim 1 , wherein the first and second printed layers have the same thickness.

5. The touch screen panel as claimed in claim 1 , wherein the touch substrate further includes outside wiring lines formed in the non-active area and coupled to the sensing electrodes.

6. The touch screen panel as claimed in claim 5 , wherein the sensing electrodes and the outside wiring lines are formed in the same layer.

7. The touch screen panel as claimed in claim 5 , wherein the touch substrate further includes reflecting patterns formed between the outside wiring lines.

8. The touch screen panel as claimed in claim 5 , wherein the outside wiring lines include one or more of Ag, Ni, Cu, Mo/Al/Mo, or an Ag—Pd—Cu alloy.

9. The touch screen panel as claimed in claim 1 , wherein the adhesive layer is formed of an optically clear adhesive.

10. The touch screen panel as claimed in claim 1 , wherein the adhesive layer has a thickness of about 50 μm to about 200 μm.

11. The touch screen panel as claimed in claim 1 , wherein a light scattering layer is formed on at least one surface of the first printed layer and the second printed layer.

12. The touch screen panel as claimed in claim 1 , wherein the light scattering layer is an organic thin film or an optical film on whose surface concavo-convex patterns are formed.

13. The touch screen panel as claimed in claim 1 , wherein a reflecting layer is formed between the second printed layer and the touch substrate.

14. The touch screen panel as claimed in claim 1 , wherein the touch substrate is an upper substrate of a display panel.

15. The touch screen panel as claimed in claim 1 , wherein the sensing electrodes include first sensing electrodes formed to be coupled in a first direction and second sensing electrodes formed to be coupled in a second direction that intersects the first direction.

16. The touch screen panel as claimed in claim 1 , wherein the one surface of the adhesive layer, the first surface of the first printed layer, the other surface of the adhesive layer, and the first surface of the second printed layer are parallel with one another and with the plane of the surface of the touch substrate.
