Abstract
An embodiment disclosed herein provides a sensing unit that senses a touch corresponding to a capacitance formed by a first electrode and a second electrode. The first electrode includes a first driving electrode pattern and a first sensing electrode pattern, the first sensing electrode pattern being disposed in the first driving electrode pattern, the second electrode includes a second driving electrode pattern and a second sensing electrode pattern, the second driving electrode pattern being disposed in the second sensing electrode pattern. A first capacitive coupling is formed corresponding to the first touch electrode and the first sensing electrode, a second capacitive coupling is formed corresponding to the second driving electrode and the second sensing electrode, and a third capacitive coupling is formed corresponding to the first touch electrode and the second sensing electrode.
