Abstract
A TFT LCD and the method of making the same are provided to prevent short circuits occurred between metal lines and transparent pixel electrodes. An insulating layer is provided to overlay the entire metal layer except the intersection areas for forming contact windows. Then, the transparent conductive layer is provided to form pixel electrodes and interconnection lines. Thus, even transparent conductive layer is not etched clearly and forming residuals, the residuals will not cause short circuits between the metal lines and transparent pixel electrodes. Eventually, the production yield rate can be increased. Moreover, a second metal layer is deposed under the transparent conductive layer to reduce the resistance of the interconnection lines.
