A thin film transistor array substrate for a liquid crystal display comprises a gate line and a data line formed in a display region, a gate connecting line and a data connecting line formed in a PAD region, and a TFT formed at an intersection between the gate line and the data line. The method does not impose any limitation on the geometry of the device, on mesh elements, or on the orientation of the anisotropy.
