Abstract
A touch screen panel provided in an image display device. The touch screen panel includes: a transparent substrate; a plurality of first sensing patterns on the transparent substrate and coupled to each other along a first direction; a first insulating film on the first sensing patterns; a plurality of second sensing patterns on the first insulating film and coupled to each other along a second direction, the first and second sensing patterns being alternately arranged not to overlap with each other; and a second insulating film on the second sensing patterns, wherein the first insulating film and the second insulating film are composed of materials having different optical refractive indexes.

A touch screen panel comprising:
- a transparent substrate;
- a plurality of first sensing patterns on the transparent substrate and coupled to each other along a first direction;
- a first insulating film on the first sensing patterns;
- a plurality of second sensing patterns on the first insulating film and coupled to each other along a second direction crossing the first direction, the second sensing patterns being alternately arranged with the first sensing patterns to not overlap with the first sensing patterns;
- and
- a second insulating film on the second sensing patterns,
- wherein the first insulating film and the second insulating film are composed of materials having different optical refractive indexes, and
- wherein the first insulating film is composed of a material having an optical refractive index greater than that of the second insulating film.
