1. 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, andwherein the first insulating film is composed of a material having an optical refractive index greater than that of the second insulating film.
