Patent ID: 8703514

Claim:
A method for manufacturing an active array substrate, comprising: forming a first patterned metal layer on a substrate, the first patterned metal layer comprising a data pad; sequentially forming a semiconductor layer, an insulating layer and a second metal layer to cover the first patterned metal layer; forming a patterned photoresist layer on the second metal layer, wherein the patterned photoresist layer comprises a first portion having a surrounding portion and an opening encircled by the surrounding portion, the opening exposing a portion of the second metal layer and aligned with the data pad; patterning the second metal layer, the insulating layer and the semiconductor layer to form a second patterned metal layer, a patterned insulating layer and a patterned semiconductor layer, and removing a portion of the patterned photoresist layer, wherein a portion of the second patterned metal layer, a portion of the patterned insulating layer and a portion of the patterned semiconductor layer form a stacked structure having a through hole exposing a portion of the data pad, and the stacked structure covers an edge of the data pad; heating the other portion of the patterned photoresist layer such that the other portion of the patterned photoresist layer is fluidized and transformed into a protective layer to cover a side wall of the second patterned metal layer, a side wall of the patterned insulating layer, a side wall of the patterned semiconductor layer, the stacked structure and a portion of the first patterned metal layer; and forming a pixel electrode on the substrate and the protective layer, wherein the pixel electrode is electrically connected to another portion of the first patterned metal layer exposed out of the protective layer.
