Abstract
A high-quality thin-film transistor array. The gate insulating film below the pixel electrode is etched off in its entirely or along a slit extending along a drain bus line in order to simultaneously remove the residual a-Si produced due to defective patterning. The insulating film is interposed between a drain bus line and a pixel electrode to form a boundary separating layer therebetween. The reject ratio is suppressed by reducing the occurrence of point defects of semi-bright spots, ascribable to capacitative coupling to the pixel electrodes as a result of interconnection of the residual a-Si produced by defective patterning to the drain bus line.
