Abstract
A touch sensitive in-plane switching (IPS) liquid crystal display (LCD) includes a liquid crystal layer, an active-matrix transistor layer with an electrode pair, a color filter substrate, and a sensing electrode layer. The sensing electrode layer may be disposed above or below the color filter substrate, and the sensing electrode layer may include two parts that are disposed above and below the color filter layer respectively.
