ABSTRACT:
A touch display panel includes a first substrate, a second substrate, a third substrate, a liquid crystal layer disposed between the second and the third substrates, a pixel array disposed between the liquid crystal layer and the third substrate, an opposite electrode, color filter patterns, a first sensing electrode, and a second sensing electrode. The first, the second, and the third substrates are disposed in parallel. The color filter patterns and the opposite electrode that are disposed between the liquid crystal layer and the second substrate are respectively disposed on opposite sides of the second substrate. Some color filter patterns are piled to form touch points. The first sensing electrode on the first substrate faces the second substrate. The second sensing electrode covers the touch points and some color filter patterns. A height of the touch points is less than a gap between the first and the second substrates.
