View Patent ↗A liquid crystal display (LCD) element with a defect repairing function and a defect repairing method of the same. In an embodiment of the invention, a pixel is associated with a plurality of scan lines and a plurality of data lines. Along with separate spare lines, melting connection can be obtained to form a circuit path and to compensate for broken wires. A single pixel can also have a plurality of subpixels with spare conduction ports and meltable joints so that defective electrodes can be separated. The spare conduction ports can be melted and connected so that other subpixels support and compensate for the defective subpixel to minimize pixel signal loss.
