Abstract

A touch screen panel for an image display device or the like. The touch screen panel includes a transparent substrate; a plurality of first sensing patterns on the transparent substrate; an insulating layer on the first sensing patterns; a plurality of second sensing patterns on the insulating layer; and a plurality of metal patterns on the insulating layer and coupled to the first and second sensing patterns at edge portions of a region in which the first and second sensing patterns are formed. The metal patterns electrically couple the first and second sensing patterns to position detecting lines on the transparent substrate. The touch screen panel further includes first conductive patterns below the metal patterns positioned on edge portions of the insulating layer.
