ABSTRACT:
First pixel electrodes and scan signal electrodes are formed in the same plane, and the first pixel electrodes and video signal electrodes are insulated and separated from each other by gate SiN films. Additional capacitors are formed by second pixel electrodes which are connected to the first pixel electrodes through apertures formed in the gate SiN films and which may be cut by a laser beam, and the scan signal electrodes. Thus, a short circuit defect between the electrodes is prevented, a highly reliable additional capacitor is attained, break of wiring is reduced and an aperture factor can be improved by expanding a width of the first pixel electrode. Thus, a multi-tonality and highly fine liquid crystal display device can be manufactured with a high yield.
