A touch sensing device includes a substrate, a first electrode, a second electrode, a third electrode, a fourth electrode. The first electrode receives a first triggering signal. The second electrode selectively receives the first triggering signal and a second triggering signal. The first electrode and the second electrode are parallelly disposed on the substrate. The third electrode senses contact touch event according to the first triggering signal to generate a first sensing signal. The fourth electrode selectively senses the contact touch event according to the first triggering signal to generate the first sensing signal and senses contactless touch event according to the second triggering signal to generate a second sensing signal. The third electrode and the fourth electrode are parallelly disposed on the substrate, and the third electrode and the fourth electrode are vertically disposed to the first electrode and the second electrode.
