DISPLAY PANEL, ACTIVE MATRIX SUBSTRATE, AND METHOD FOR REPAIRING WHITE DEFECT OF DISPLAY PANEL

原文（中国語）

A method for repairing a white defect of a LCD panel includes providing a substrate defining a plurality of pixel areas by: forming a base, a first metal layer, a first insulation layer, a channel layer, a second metal layer, and a second insulation layer; forming a first conductive layer on the second insulation layer; forming a first through hole in the second insulation layer by laser, extending the first through hole through the second insulation layer and separating the drain electrode into two parts; covering a third insulation layer; forming a second conductive layer on the third insulation layer; penetrating the first conductive layer by laser to coupling the second conductive layer to the first conductive layer; and forming a second through hole in the third insulation layer.
