Abstract:
A method of manufacturing a liquid crystal display device driving with fringe field between counter and pixel electrodes, comprising the steps of:depositing a first transparent conductive layer on a transparent insulating substrate and etching the first transparent conductive layer using a first mask, thereby forming a counter electrode; forming a first insulating layer as a protection layer on the substrate formed the counter electrode; depositing a first metal layer on the first insulating layer and etching the first metal layer using a second mask, thereby forming a gate bus line and a common electrode line, the common electrode line being in contact with the counter electrode; 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; etching the second insulating layer using a third mask to form an etch stopper; forming a doped amorphous silicon layer and a second metal layer on the substrate formed on the etch stopper; etching the second metal layer using a fourth mask to form source/drain and a data bus line; 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; forming a passivation layer on the substrate formed on the ohmic layer and the channel layer; etching the passivation layer using a fifth mask to open a pad portion of the gate bus line, a portion of the data bus line and the source; and depositing a second transparent conductive layer on the passivation and etching the second transparent conductive layer using a sixth mask, 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.
