Abstract

A liquid crystal display device and a method for manufacturing the same are disclosed. The liquid crystal display device comprises gate and data lines arranged to cross each other on a substrate to define a plurality of pixels; a pixel electrode formed in each of the plurality of pixels; a common electrode forming an electric field together with the pixel electrode, patterned to sense a touch of a user; a sensing line discontinuously formed on the common electrode and electrically connected with the common electrode; a jump line formed below the common electrode to electrically connect discontinuous portions of the sensing line with one another; and first and second connection electrodes for electrically connecting the jump line with the sensing line, wherein the first connection electrode is connected with the jump line, and the second connection electrode is connected with the sensing line and the first connection electrode respectively. Because the common electrode is used as a sensing electrode, an independent touch screen is not needed on the liquid crystal panel.
