ABSTRACT:
A thin film transistor (TFT) array panel, a liquid crystal display (LCD), and a method of repairing a TFT array panel with a defective pixel is disclosed. When a white defect occurs such that a pixel is always in a white state, a corresponding pixel electrode is supplied with the predetermined voltage applied to a corresponding storage electrode line so that the pixel becomes permanently dark, which may not be easily detected. The connection between the pixel electrode and the storage electrode line is provided by illuminating a laser beam from a common electrode panel through a contact hole in the TFT array panel to electrically couple the storage electrode and the pixel electrode. Advantageously, a backlight unit or chassis does not need to be separated or disassembled from the LCD when repairing the defect. Furthermore, the color filter stripes and the light blocking member are not damaged, thereby improving the reliability of the repair.
