摘要:
A method for manufacturing an active matrix display apparatus comprising: forming picture element electrodes disposed in a matrix at the inner surface of either one of a pair of substrates, switching elements electrically connected to the picture element electrodes respectively, spare switching elements disposed close to the picture element electrodes in a non-conductive state respectively, and connections, each including an extension end of each of the spare switching elements and a metal piece electrically connected to one end of each of the picture element electrodes, the extension end and metal piece being disposed opposite to each other in a non-conductive state; applying a drive signal to a display medium via the picture element electrodes and opposite electrodes thereby detecting a defect in the switching element; and irradiating energy onto the connection between the picture element electrode connected to the switching element, the defect of which has been detected, and the spare switching element, thereby electrically connecting the picture element electrode with the spare switching element, whereby the apparatus can be provided with a high yield.
