ABSTRACT:
An active matrix device has pixel electrodes (40), each of which is divided into a plurality of divisional pixel electrodes (41, 42). Each divisional pixel electrode (41, 42) has a corresponding switching element (31, 32). A junction bridges adjacent ones of the divisional pixel electrodes (41, 42), and at least one spare switching element (34) is disposed in proximity to the junction. The junction has a pair of metal pieces (44, 45) electrically connected to the respective pixel electrodes (41, 42), an output terminal (74) of the spare switching element (34), and a joint metal layer (46) on which both of the metal pieces (44, 45) and the output terminal (74) of the spare switching element (34) are superposed with an insulating film (54) placed therebetween.
