Claim Text:
1. A liquid crystal display having an embedded touch panel, the liquid crystal display comprising: a color filter substrate; an array substrate; a liquid crystal molecule layer between the color filter substrate and the array substrate; and a touch panel integrated with the color filter substrate, wherein a plurality of first transfer pads are arranged on the color filter substrate and a plurality of second transfer pads are arranged on the array substrate, wherein locations of the first transfer pads correspond to locations of the second transfer pads, wherein the first transfer pads are electrically connected with the second transfer pads, and wherein the first and second transfer pads are used to transmit a touch control signal to the touch panel; and the color filter substrate comprises: a substrate; a black matrix layer arranged on the substrate, wherein the black matrix layer comprises a plurality of black matrix units; a first metal layer arranged on the black matrix layer, wherein the first metal layer comprises: a plurality of first sensing electrodes continuously arranged in a longitudinal direction, and a plurality of second sensing electrodes spaced by the continuously arranged first sensing electrodes in a transverse direction; a color filter layer formed on the first metal layer, wherein the color filter layer covers both the black matrix layer and the first metal layer and fills a space between the black matrix units; a via hole exposing a portion of the first metal layer in the color filter layer; and a second metal layer formed in the via hole and over the color filter layer to form a metal bridge, wherein the metal bridge contacts the second sensing electrodes, so that the touch panel formed by the first metal layer, the second metal layer, and the color filter layer between the first and second metal layers; or, the color filter substrate comprises: a substrate; a black matrix layer arranged on the substrate, wherein the black matrix layer comprises a plurality of black matrix units; a first metal layer arranged on the black matrix layer, wherein the first metal layer comprises: a plurality of first sensing electrodes continuously provided in a longitudinal direction; and a plurality of second sensing electrodes spaced by the continuously provided first sensing electrodes in a transverse direction; an organic layer formed on the first metal layer, wherein the organic layer covers both the black matrix layer and the first metal layer and fills a space between the black matrix units; a via hole which exposing a portion of the first metal layer in the organic layer; a second metal layer formed in the via hole and over the organic layer to form a metal bridge, wherein the metal bridge contacts the second sensing electrodes, so that a touch control layer being formed by the first metal layer, the second metal layer and the organic layer between the first and second metal layers, thereby integrating the touch panel into the color filter substrate; and a color filter layer arranged on both the second metal layer and the organic layer.
