Abstract
In an active liquid crystal display element which operates in a normally white mode, there is formed a shorting metal layer which overlaps each pixel electrode and a source bus adjacent thereto. In those portions of the pixel electrode and the source bus overlapping the shorting metal layer there are formed weld metal layers. The pixel electrode of a defective pixel is connected to the corresponding source bus by welding the weld metal layers and the shorting metal layer through irradiation with laser beams to the above-mentioned overlapping portions. As a result of this, the defective pixel becomes a black defect when the liquid crystal display element operates.
