ABSTRACT:
There is disclosed a method of manufacturing a flat display in which a switching element (TFT) having caused a display pixel defect can securely be repaired. The flat display of the present invention is formed by forming a semiconductor layer and an auxiliary capacity electrode in the same layer on a glass substrate, forming a gate insulating film on a top surface, forming a gate electrode and an auxiliary capacity feeder in the same layer on the top surface, forming an interlayer insulating film on a top surface, and forming a source electrode and drain electrode on a top surface. Since a wiring portion between the auxiliary capacity electrode and the pixel electrode is irradiated with laser to increase the resistance of a wiring portion, the pixel electrode fails to be influenced by a voltage of the auxiliary capacity feeder, occurrence of the display pixel defect can be reduced, and manufacture yield can be enhanced.
