Abstract
A touch screen panel includes: a first substrate and a second substrate, which face each other with respect to a liquid crystal interposed therebetween; and a touch sensor interposed between the first substrate and the second substrate. The touch sensor includes: a plurality of first touch signal lines disposed on the first substrate and extending in a first direction; a protective layer disposed on the first substrate, the protective layer including a dielectric material and substantially the plurality of first touch signal lines; a plurality of contact pads disposed on the protective layer; a plurality of second touch signal lines disposed on the second substrate and extending in a second direction perpendicular to the first direction; and a plurality of touch sensor spacers electrically connected to the plurality of second touch signal lines. A gap between the touch sensor spacers and the plurality of contact pads is defined, and the spacers are disposed to face the plurality of contact pads.
