  • Patent number: 8643812
    Abstract: A display substrate has first and second conductive layers separated from one another by an insulation layer. The first and second conductive layers are used to integrally form on the display substrate, pixel units in a relatively central display area of the substrate and integrated gate driving circuitry as well as associated wirings thereof in one or more peripheral areas. The first and second conductive layers are covered by a first protection layer made of a first electrically insulative material. A second and supplementing protection layer is provided on top of the first protection layer. The supplementing protection layer (buffer layer) is formed of a material different from that of the first protection layer so as to provide supplemental resistance against corrosive chemical agents and supplemental resistance against formation of cracks.
