1. A touch screen panel comprising:

  • a substrate;

    a plurality of metal patterns comprising first metal patterns and second metal patterns;

    a plurality of first coupling patterns on the substrate;

    a dielectric layer covering the first coupling patterns and the substrate, the dielectric layer having contact holes corresponding to end portions of the first coupling patterns;

    a plurality of first sense cells arranged in a first direction on the dielectric layer and separated from the substrate by the dielectric layer, the first sense cells being arranged in a display area of the substrate;

    a plurality of second sense cells arranged in a second direction on the dielectric layer, the second sense cells being arranged in the display area of the substrate; and

    a dummy pattern on a same layer with the first sense cells and the second sense cells,wherein a ground voltage is applied to the dummy pattern,wherein adjacent ones of the first sense cells are electrically coupled to each other along the first direction by the first coupling patterns at where the first coupling patterns are exposed by the contact holes,wherein at least two of the first coupling patterns electrically couple two adjacent ones of the first sense cells to each other,wherein the first metal patterns are electrically coupled to the first sense cells, and the second metal patterns are electrically coupled to the second sense cells,wherein the metal patterns are in a peripheral region of the display area of the substrate,wherein the first coupling patterns and the metal patterns are formed in a same layer, andwherein the end portions of the first coupling patterns are inclined at an oblique angle with respect to the first direction.
