Abstract

A touch screen panel includes: a substrate; a sensor that is disposed at the center of the substrate; a metal wire pattern that is disposed at a periphery of the sensor and that has at least a portion that is connected to the sensor; an insulation layer that covers the metal wire pattern; and a ground line that is disposed between the edge of the substrate and the metal wire pattern.

Claims

1. A touch screen panel comprising:

a substrate;

a sensor at the center of the substrate;

a metal wire pattern at a periphery of the sensor and having at least a portion connected to the sensor;

an insulation layer covering the metal wire pattern; and

a ground line between an edge of the substrate and the metal wire pattern.

2. A display device comprising:

the touch screen panel of claim 1; and

a display panel facing the substrate of the touch screen panel.

3. The touch screen panel of claim 1, further comprising:

a window member facing the substrate with the sensor interposed therebetween; and

an adhesive layer filling space between the window member and the substrate.

4. A display device comprising:

the touch screen panel of claim 3; and

a display panel facing the substrate of the touch screen panel.

5. The touch screen panel of claim 3, further comprising a light blocking layer formed in an area of the window member facing the metal wiring pattern.

6. A display device comprising:

the touch screen panel of claim 5; and

a display panel facing the substrate of the touch screen panel.

7. The touch screen panel of claim 1, wherein the ground line is extended from between the edge of the substrate and the metal wire pattern, onto the insulation layer covering the metal wire pattern.

8. A display device comprising:

the touch screen panel of claim 7; and

a display panel facing the substrate of the touch screen panel.
