Abstract:
1. A method of manufacturing a liquid crystal display, comprising: forming a gate line including a gate electrode on a substrate; forming a gate insulating layer on the gate line; sequentially forming a semiconductor layer, an amorphous silicon layer, and a data metal layer on the entire surface of the gate insulating layer; aligning the edges of the semiconductor layer and the data metal layer by etching the semiconductor layer, the amorphous silicon layer, and the data metal layer; forming a transparent conductive layer on the gate insulating layer and the data metal laver; forming a first pixel electrode and a second pixel electrode by patterning the transparent conductive layer; forming a data line including a source electrode, a drain electrode, and an ohmic contact layer by etching the data metal layer and the amorphous silicon layer, using the first pixel electrode and the second pixel electrode as a mask, and exposing the semiconductor between the source electrode and the drain electrode; applying a plasma process to the exposed semiconductor; forming a nitrified silicon film on the first pixel electrode, the second pixel electrode, and the exposed semiconductor, forming a spacer on the nitrified silicon film corresponding to the exposed semiconductor, and forming a buffer layer by etching the nitrified silicon film, using the spacer as a mask, wherein the first pixel electrode is in contact with the drain electrode and the second pixel electrode is in contact with the source electrode.
