Abstract:
A method of manufacturing a liquid crystal display panel which includes a thin film transistor having a channel layer, an etching stopper disposed on the channel layer, and source and drain layers electrically contacting with and disposed on the channel layer, comprising the steps of:providing the etching stopper on the channel layer, the etching stopper having ends and a length in a channel width direction; providing a source/drain layer on the channel layer and the etching stopper, the source/drain layer having a width in the channel width direction, wherein the length of the etching stopper is longer in the channel width direction than the width of the source/drain layer; simultaneously etching at least the etching stopper and the source/drain layer to form the source and drain layers; and removing the ends of the etching stopper.
