A touch screen panel comprising:
- a first touch electrode disposed on a substrate and extending in a first direction, the first touch electrode comprising first mesh patterns formed of crossing metal wirings comprising fine patterns;
- and
- a second touch electrode disposed on the substrate and extending in a second direction crossing the first direction, the second touch electrode comprising second mesh patterns formed of crossing of metal wirings comprising fine patterns,
- wherein a pitch of the fine patterns of the first mesh patterns and/or the second mesh patterns is less than 150 nm.
A touch display device comprising:
- a display panel configured to display an image;
- and
- a touch screen panel disposed on the display panel, the touch screen panel comprising:
- a first touch electrode disposed on a substrate and extending in a first direction, the first touch electrode comprising first mesh patterns formed of crossing metal wirings comprising fine patterns;
- and
- a second touch electrode disposed on the substrate and extending in a second direction crossing the first direction, the second touch electrode comprising second mesh patterns formed of crossing of metal wirings comprising fine patterns,
- wherein a pitch of the fine patterns of the first mesh patterns and/or the second mesh patterns is less than 150 nm.
A method of manufacturing a touch screen panel, the method comprising:
- forming a first protection layer on a substrate;
- forming, on the first protection layer, a first touch electrode extending in a first direction, the first touch electrode comprising first mesh patterns formed of crossing metal wirings comprising fine patterns, the first protection layer being, in a third direction crossing the first direction, between the first touch electrode and the substrate;
- forming, on the first protection layer, a second touch electrode extending in a second direction crossing the first direction, the second touch electrode comprising second mesh patterns formed of crossing metal wirings comprising fine patterns, the first protection layer being, in the third direction, between the second touch electrode and the substrate;
- and
- forming a second protection layer on the first touch electrode and the second touch electrode.
