a plurality of second coupling patterns on the transparent substrate aligned in a second direction and being spaced from the first coupling patterns;
a dielectric layer on the first and second coupling patterns and having first and second contact holes respectively corresponding to end portions of the first and second coupling patterns;
a plurality of first sense cells arranged in rows extending in the first direction on the dielectric layer; and
a plurality of second sense cells arranged in columns extending in the second direction on the dielectric layer,wherein adjacent ones of the first sense cells are electrically coupled to each other through the first coupling patterns exposed by the first contact holes, and adjacent ones of the second sense cells are electrically coupled to each other through the second coupling patterns exposed by the second contact holes.

Abstract
A touch screen panel includes first and second sense cells on a same layer and coupling patterns that couple adjacent ones of the first sense cells and adjacent ones of the second sense cells to each other, respectively. The coupling patterns do not cross with each other, thereby improving the ability of the coupling patterns to withstand static electricity. A dummy line formed of a same material as the sense cells may be formed between the first and second sense cells, and the dummy line is electrically coupled to a guard ring located in an area outside of a display area of the touch screen panel, making it possible to overcome the effects of static electricity applied to the front surface of the touch screen panel as well as the side surface thereof.
