<p>On the inside surface of one of a pair of opposed transparent substrates forming an active liquid crystal substrate there are formed first and second insulating layers (22, 24). Between the insulating layers there are provided transparent pixel electrodes (15) arranged in a matrix form and source lines (19) corresponding to respective columns of the pixel electrodes. A short-circuit metal layer (28) is formed on the substrate, the opposite ends of thre metal layer (28) underlying a marginal portion of each pixel electrode (15) and the source line (19) adjacent thereto, respectively, but separated therefrom by the first insulating layer (22). In these overlapping regions welding metal pads (29, 31) are formed on the pixel electrode (15) and the source line (19). Other welding metal pads (32, 33) of a ductile metal are formed on the second insulating layer (24) right above the first-mentioned welding metal pads (29, 31), respectively. In the case of a white-defect pixel, laser beams are applied to the two overlapping regions to destroy the first and second insulating layers (22, 24) and fuse metals of three layers together, by which the pixel electrode (15) of the defective pixel is short-circuited to the corresponding source line (19). <IMAGE></p> |
