Pixel and method for pixel repair

A method of repairing a pixel, comprising the steps of:

• forming a first metal layer on part of a transparent substrate;
• forming a first hole to penetrate the first metal layer and expose the transparent substrate;
• forming an insulating layer to cover the first metal layer and the transparent substrate;
• forming a second metal layer on the insulating layer;
• forming an organic insulating layer to cover the second metal layer;
• removing part of the organic insulating layer to form a second hole therein, wherein the second hole is located directly above the first hole;
• forming a first transparent electrode on the organic insulating layer extending into the second hole;
• passing a first laser beam through the first hole to weld the second metal layer and the first transparent electrode in the second hole;
• forming a third hole in the organic insulating layer above the first metal layer;
• and
• forming a second transparent electrode on the organic insulating layer extending into the third hole, wherein the second transparent electrode is a common electrode.
