Abstract:
1. A method for repairing a pixel of a liquid crystal display device, comprising following steps: (A) providing a substrate having a plurality of pixels thereon, wherein each pixel comprises: a switch having a gate, a source and two drains; a pixel electrode; and a floating conductive line; the pixel electrode electrically connects to the switch through the drain, and the floating conductive line crosses the two drains without electrical connection; (B) cutting one of the two drains, wherein the location of the cut on the drain is not between the crossed position of the drain and the floating conductive line and the switch; and (C) checking the pixel through charging the source and the gate on the substrate; (D) cutting the uncut drain, wherein the location of the cut on the conductive line is between the crossed position of the drain and the floating conductive line and the switch; and (E) welding the two drains and the floating conductive line together to make the two drains electrically connect to the floating conductive line.
