1. A touch sensitive in-plane switching (IPS) liquid crystal display (LCD), comprising:
- a liquid crystal layer;
an active-matrix transistor substrate disposed below the liquid crystal layer;
an electrode pair disposed or set on the active-matrix transistor substrate, the electrode pair comprising a pixel electrode and a common electrode, wherein a laterally horizontal electric field is generated between the pixel electrode and the common electrode for controlling orientation of liquid crystals of the liquid crystal layer;
a color filter substrate disposed above the liquid crystal layer; and
a sensing electrode layer disposed above the color filter substrate.
