An active matrix substrate (10) comprises a transistor (12), a pixel electrode (17) connected to one of conductive electrodes (8) of the transistor (12), a hold capacitor wiring (18), a lead wiring (7) extended from the one of conductive electrodes (8) of the transistor (12), and a repair wiring (19) extended from the hold capacitor wiring (18) and overlapping a part of the lead wiring (7) with an insulating layer in between. This enables a TFT failure (for example, a short circuit between a source electrode and a drain electrode) to be repaired, high-speed display to be performed, and power consumption to be suppressed. L'invention concerne un substrat à matrice active (10) qui comprend un transistor (12), une électrode de pixel (17) reliée à l'une parmi des électrodes conductrices (8) du transistor (12), un câblage de condensateur de maintien (18), un câblage de fil (7) qui fait saillie dudit électrode conductrice (8) du transistor (12), et un câblage de réparation (19) qui fait saillie du câblage de condensateur de maintien (18) et chevauche une partie du câblage de fil (7), une couche isolante se trouvant entre ceux-ci. Ceci permet de réparer une défaillance de transistor TFT (par exemple un court-circuit entre une électrode de source et une électrode de drain), d'effectuer un affichage à haute vitesse et de diminuer la consommation d'énergie.
