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 metal layer and a first metal layer on a transparent insulating substrate in sequence and patterning the first transparent metal layer and the first metal layer using a first mask, thereby forming a gate bus line and defining a pattern portion having counter electrode and common signal line regions; depositing a gate insulating layer, an amorphous silicon layer and a silicon nitride layer on the overall substrate sequentially and patterning the silicon nitride layer using a second mask, thereby forming a etch stopper on the gate bus line; patterning the pattern portion using a third mask so as to be exposed in the shape of plate, thereby forming a counter electrode consisting of the first transparent metal layer and a common signal line consisting of the first metal layer and opening pad portions; depositing a doped amorphous silicon layer and a second metal layer on the overall substrate sequentially and patterning the second metal layer using a fourth mask, thereby forming a data bus line, a source and a drain; etching the doped amorphous silicon layer and the amorphous silicon layer using the source and the drain as a mask to form an ohmic layer and a channel layer; forming a passivation layer on the overall substrate and etching the passivation layer so as to expose a portion of the source, thereby forming a contact hole; and depositing a second transparent metal layer on the passivation layer so as to fill the contact hole and patterning the second transparent metal layer using a sixth mask, thereby forming a pixel electrode in the shape of comb, the pixel electrode overlapping with the counter electrode and being in contact with the source.
