Patent ID: 7390734

Claim:
A method for manufacturing a thin film transistor (TFT) substrate, comprising: providing a glass substrate; forming a first thin film transistor, a second thin film transistor, and an electrode pad on the glass substrate, wherein the electrode pad is electrically connected with the first thin film transistor and the second thin film transistor; forming a first color filter and a second color filter on the first thin film transistor and the second thin film transistor respectively; forming a first pixel electrode and a second pixel electrode on part of the first color filter and the second color filter respectively, wherein the first pixel electrode and the second pixel electrode are electrically connected with the first thin film transistor and the second thin film transistor respectively, and the first pixel electrode is apart from the second pixel electrode so that a surface border between the first color filter and the second color filter is exposed out of the first pixel electrode and the second pixel electrode; forming a first photo spacer and a plurality of second photo spacers on the surface border between the first color filter and the second color filter and the electrode pad respectively, wherein the second photo spacers are deposited dividedly; and forming a conductive layer adapted to cover the top surfaces of the second photo spacers, the inward surfaces of the second photo spacers, and part of the electrode pad between the second photo spacers, wherein the conductive layer is electrically connected with the electrode pad, and the outward side surfaces of the second photo spacers are exposed out of the conductive layer.
