A touch screen panel and manufacturing method thereof are disclosed. In one aspect, the touch screen panel includes a substrate, a plurality of first sensing electrodes formed over the substrate in a first direction and a plurality of second sensing electrodes formed over the substrate in a second direction. The touch screen panel also includes at least one insulating layer formed at intersections between the first and second sensing electrodes. The insulating layer has a line shape that extends in one of the first direction or the second direction and crosses the first or second sensing electrodes.
