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. In one class of embodiments, the supplementing protection layer is made of a same material as used form at least one of an alignment layer, sealing layer and spacer layer of the display substrate.

Abstract: A liquid crystal display including: a first substrate including a pixel area including a first subpixel area and a second subpixel area; a first subpixel electrode positioned in the first subpixel area and a second subpixel electrode positioned in the second subpixel area; an insulating layer formed on the first and second subpixel electrodes; a third subpixel electrode positioned in the first subpixel area and overlapping the first subpixel electrode; a fourth subpixel electrode positioned in the second subpixel area and overlapping the second subpixel electrode; a second substrate facing the first substrate; and a liquid crystal layer interposed between the first substrate and the second substrate. The first and fourth subpixel electrodes are connected to a first thin film transistor, and the second and third subpixel electrodes are connected to a second thin film transistor.
