An active matrix substrate includes a transistor, a pixel electrode
connected with one of the current-flowing electrodes of the transistor, a
storage capacitor wiring, a lead wiring extending from one of the
current-flowing electrodes of the transistor, and a repair wiring
extending from the storage capacitor wiring. The repair wiring overlaps a
portion of the lead wiring with an insulating layer interposed
therebetween. As a result, TFT defects (for example, a short circuit
between a source electrode and a drain electrode) can be repaired, and
performance of fast display and reduction in electric power consumption
can be realized.
