Abstract
A liquid crystal display panel with a repair capability that has a plurality of optical display cells arranged in a matrix format with scan lines and orthogonal data lines, at least two field effect transistors associated with each cell adapted to each operate in parallel one half of a split plate electrode. A means is provided to segregate one of the transistors when it is defective. Also, is provided a means to electrically join the parts of the plate electrode. The method involves providing the above described display panel, testing the panel and noting the existence of any defective transistors, segregating the defective transistor, and joining the parts of the split plate electrode of the cells associated with a defective transistor.
