Method of manufacturing liquid crystal display device
A method of manufacturing a liquid crystal display device driving with fringe field between counter and pixel electrodes, by the following steps. First, by depositing a first transparent conductive layer on a transparent insulating substrate and etching the first transparent conductive layer, thereby forming a counter electrode. Second, by forming a first insulating layer as a protection layer on the substrate formed on the counter electrode. Third, by depositing a first metal layer on the first insulating layer and etching the first metal layer, thereby forming a gate bus line and a common electrode line, the common electrode line being in contact with the counter electrode. Fourth, by forming a gate insulating layer, an amorphous silicon layer and a second insulating layer on the substrate formed on the gate bus line and the common electrode line. Fifth, by etching the second insulating layer to form an etch stopper. Sixth, by forming a doped amorphous silicon layer and a second metal layer on the substrate formed on the etch stopper. Seventh, by etching the second metal layer to form source/drain and a data bus line. Eighth, by etching the doped amorphous silicon layer and the amorphous silicon layer using the source/drain as a mask to form an ohmic layer and a channel layer. Ninth, by forming a passivation layer on the overall substrate formed on the ohmic layer and the channel layer. Tenth, by etching the passivation layer to open a pad portion of the gate bus line, a portion of the data bus line and the source. Finally, by depositing a second transparent conductive layer on the passivation and etching the second transparent conductive layer, thereby forming a pixel electrode, the pixel electrode being in contact with the opened source, the data bus line, and the pad portion of the gate bus line.
