  • Active matrix liquid crystal display device
    Patent number: 6515720
    Abstract: A coupling line connecting a pixel electrode to a source electrode and a storage capacitance electrode includes a wiring portion which does not overlap a storage capacitance line or a storage capacitance electrode. Thus, the wiring portion is exposed when viewed from the rear side of the array substrate. Therefore, even if a short circuit occurs between the storage capacitance line and the coupling line or the storage capacitance electrode, a pixel including the short-circuit defect can be improved to a half-lighted state by radiating the laser beam to the wiring portion to electrically cut it.
