Thin film transistor liquid crystal display and manufacturing method thereof

摘要

A manufacturing method and the structure of a thin film transistor liquid crystal display (TFT-LCD) are disclosed. The TFT-LCD uses metal electrodes as a mask to thoroughly remove the unwanted semiconductor layer during the etching process for forming the source and drain electrodes. This manufacturing method can reduce the problems caused by the unwanted semiconductor layer, hence improving the quality of the TFT.
