Abstract

See full text

A method for repairing a white defect of a LCD panel includes providing a substrate, the substrate defining pixel areas which themselves comprise a base, a first metal layer, a first insulating layer, a semi-conductor layer, an ohmic contact layer, a source electrode, a drain electrode, and a second insulating layer; forming a through hole by laser in the second insulating layer, the through hole extending through the second insulating layer and separating the drain electrode into two spaced parts; forming a third insulating layer to cover the first conductive layers, the second insulating layer and the though hole and forming a second conductive layer by laser on the third insulating layer to couple the first conductive layer to the second conductive layer.
