ABSTRACT:
A process for repairing defects applied in producing a liquid crystal display, wherein the liquid crystal display includes a pixel array formed by a plurality of scanning lines crossing with a plurality of data lines. The process includes steps of providing an essential repair line located on one side of the pixel array, welding a first intersection point of a defecting data line and the essential repair line and a second intersection point of a normal data line adjacent to the defecting data line and the essential repair line by a first laser to achieve electrical connection, and cutting a first breaking point and a second breaking point of the essential repair line by a second laser to achieve a broken circuit, wherein the first and second intersection points are located two sides of a line segment constructed by the first and second intersection points respectively.
