Abstract
A method for manufacturing an LCD panel comprises the steps of providing a substrate having a conducting layer forming a pad and a conducting line, and an isolation layer on the pad and the conducting line, forming a planarization layer on the isolation layer above the conducting line, and a first through hole in the planarization layer, the first through hole exposing the isolation layer and aligned with the conducting line, forming a masking layer on the isolation layer above the pad, and a second through hole in the masking layer, the second through hole exposing the isolation layer and aligned with the pad, and etching the isolation layer with the masking of the planarization layer and the masking layer, whereby the isolation layer exposed by the first and second through hole is removed.
