Abstract

A manufacturing method of a touch screen panel includes: forming touch electrodes on a substrate; forming an insulating layer on the touch electrodes; disposing an adhesive layer on the touch electrodes and the insulating layer, the adhesive layer including an adhesive protection film adhered on one surface of the adhesive layer facing away from the touch electrodes; and forming a conductive layer on the adhesive protection film.

Claims (25)

1. A method of manufacturing a touch screen panel, comprising:

forming touch electrodes on a substrate;

forming an insulating layer on at least a part of the touch electrodes;

disposing an adhesive layer on the touch electrodes and the insulating layer, the adhesive layer exposing at least a part of the insulating layer and at least a part of the touch electrodes around the insulating layer, the adhesive layer further comprising an adhesive protection film adhered on one surface of the adhesive layer facing away from the touch electrodes;

forming a conductive layer on the adhesive protection film, and the insulating layer and the touch electrodes that are exposed by the adhesive layer; and

removing the conductive layer formed on the protection film by removing the adhesive protection film.

2. The method of claim 1 , wherein the forming the touch electrodes comprises:

forming first touch electrodes extending in a first direction not overlapping each other; and

forming second touch electrodes in a second direction,

wherein the first touch electrodes and the second touch electrodes are alternately disposed not overlapping each other, and

wherein the touch screen panel comprises:

first connecting portions electrically connecting two of the first touch electrodes that are adjacent to each other in the first direction; and

second connecting portions electrically connecting two of the second touch electrodes that are adjacent to each other in the second direction.

3. The method of claim 2 , wherein the forming the insulating layer comprises:

forming the insulating layer in an island-shape in areas where the plurality of first connecting portions crosses the second connecting portions.

4. The method of claim 3 , wherein the forming the adhesive layer comprises:

forming the adhesive layer to expose the insulating layer and the second touch electrodes adjacent to the insulating layer.

5. The method of claim 4 , wherein the second touch electrodes are exposed by openings formed in the adhesive layer in the second direction.

6. The method of claim 5 , wherein the first connecting portions are disposed on the same layer as the first touch electrodes, and

the first connecting portions is integrally formed with the first touch electrodes.

7. The method of claim 1 , wherein the second connecting portions are disposed on the insulating layer.

8. The method of claim 7 , wherein the first connecting portions and the second connecting portions are insulated by the insulating layer.

9. The method of claim 1 , further comprising:

attaching a cover substrate onto a surface of the adhesive layer from which the protection film is removed.

10. The method of claim 1 , wherein the adhesive layer includes an optically clear adhesive (OCA) film.
