Abstract
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.
