ABSTRACT:
The present invention discloses a method of manufacturing a liquid crystal display device, including depositing a first metal layer on a transparent substrate; patterning the metal layer to form a gate line, the gate line having a gate electrode portion; depositing sequentially an insulating layer, an amorphous silicon layer and a doped amorphous silicon layer on the exposed surface of the transparent substrate while covering the gate line; patterning the amorphous silicon layer and the doped amorphous silicon layer to form a semiconductor island; depositing a second metal layer on the exposed surface of the insulating layer while covering the semiconductor island; patterning the second metal layer to form a source electrode, a drain electrode, and a capacitor electrode, the drain electrode spaced apart from the source electrode; etching the doped amorphous silicon layer of the semiconductor island to from an active area; forming a passivation film over the whole surface of the substrate while covering the source electrode, the drain electrode and the capacitor electrode; depositing a transparent conductive material layer on the passivation film; applying a negative photoresist on the transparent conductive material layer; performing a back side exposure to form a first exposed portion of the negative photoresist; aligning a patterning mask with the negative photoresist; performing a front side exposure to form a second exposed portion of the negative photoresist, the second exposed portion overlapping the first exposed portion; baking the transparent conductive material layer; and patterning the transparent conductive material layer to form a pixel electrode.
