摘要： In a liquid crystal display device substrate, an insulating layer covers a thin film transistor. Another insulating layer covers a black matrix, which is formed on the insulating layer and covers the thin film transistor, a gate line, and a data line except a portion of a drain electrode. A first transparent conductive layer covers the top insulating layer and contacts the exposed portions of the drain electrode, a gate pad and a data pad. A buffer layer is formed on the first conductive layer and a color filter is formed on the buffer layer. The buffer layer is exposed by the color filter to reveal portions of the first conductive layer. A second transparent conductive layer covers the color filter and the revealed portions of the first conductive layer. The conductive layers are patterned to form pixel electrodes and double-layered gate and data pad terminals.
