Touch screen panel and method of manufacturing the same
A touch screen panel including a touch electrode disposed on a base substrate, the touch electrode including a plurality of mesh patterns formed by crossing of metal wirings. The mesh patterns include a main electrode pattern and a buffer pattern overlapping the main electrode pattern, the buffer pattern having a thickness greater than 20% of a thickness of the main electrode pattern and less than 30% of a thickness of the main electrode pattern.
1. A touch screen panel comprising a touch electrode disposed on a base substrate, the touch electrode comprising a plurality of mesh patterns formed by crossing of metal wirings,
wherein the mesh patterns comprise:
a main electrode pattern; and
a buffer pattern overlapping the main electrode pattern and having a thickness greater than 20% of a thickness of the main electrode pattern and less than 30% of a thickness of the main electrode pattern.
2. The touch screen panel of claim 1 , wherein the main electrode pattern comprises:
a barrier metal pattern comprising titanium (Ti) or molybdenum (Mo);
a main metal pattern disposed on the barrier metal pattern and comprising aluminum (Al); and
a capping metal pattern covering the main metal pattern and comprising titanium (Ti) or molybdenum (Mo).
3. The touch screen panel of claim 2 , wherein the buffer pattern comprises silicon nitride (Si 3 N 4 ).
4. The touch screen panel of claim 1 , wherein the main electrode pattern comprises:
a main metal pattern disposed on the buffer pattern and comprising aluminum (Al); and
a capping metal pattern covering the main metal pattern and comprising titanium (Ti) or molybdenum (Mo).
5. The touch screen panel of claim 4 , wherein the buffer pattern comprises titanium (Ti).
6. The touch screen panel of claim 4 , wherein the buffer pattern comprises molybdenum (Mo).
7. The touch screen panel of claim 1 , wherein the touch electrode comprises:
a first touch electrode extending in a first direction; and
a second touch electrode extending in a second direction crossing the first direction.
8. The touch screen panel of claim 7 , wherein the first touch electrode is disposed on a different layer from the second touch electrode.
9. The touch screen panel of claim 7 , wherein the first touch electrode is disposed on the same layer as the second touch electrode.
10. The touch screen panel of claim 9 , wherein:
the first touch electrode comprises a plurality of first mesh patterns separated from each other, and the second touch electrode comprises a plurality of second mesh patterns connected with each other; and
the touch screen panel further comprises a connecting electrode connecting the first mesh patterns.
