Title: Liquid crystal display having a defect repair mechanism interposed between a light shielding storage line and a light shielding output electrode

Abstract: A liquid crystal display that is subject to pixel-high defects due to manufacturing anomalies is provided with programmable repair means for each pixel electrode. In one embodiment, a transistor-array substrate is provided with plural gate lines that are separated from each other by a first interval, plural data lines that are insulated from the gate lines while crossing the gate lines, and separated from each other by a second interval larger than the first interval, thereby defining plural pixel areas. Each pixel area has a corresponding pixel unit comprising a switching device, pixel electrode, and repair electrode. The repair electrode branches from a neighboring gate line and extends such that the repair electrode is in overlapping spaced-apart relation with the pixel electrode and selectively connectable to the pixel electrode. Accordingly, a pixel where a high pixel defect occurs can be repaired by selective connection with the repair electrode, thereby improving display quality of the liquid crystal display.
