Abstract

An active matrix substrate comprising picture element electrodes disposed in a matrix on a substrate, each of which is composed of divided electrodes, and an electrically conductive film on which two of said divided electrodes adjacent to each other are superposed in a manner to sandwich an insulating film therebetween so as to form a connection. The connection is irradiated with laser beams from the outside of the display apparatus when one of the divided electrodes brings about a picture element defect, so that both the divided electrodes can be electrically connected to each other, thereby attaining a correction of the picture element defect. A display apparatus using the active matrix substrate is also provided.
