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.

Display substrate, method of manufacturing the same and display device having the same

A display substrate and a display device including the same are provided. The display substrate includes a first substrate which is divided into a display portion including pixel regions and a non-display portion including a region other than the display portion. Color filters are formed in the pixel regions of the substrate to respective thicknesses. At least one stepped pattern is formed on the non-display portion of the substrate and from the same material as used to form at least one of the color filters. The stepped patterns are formed at an area occupancy density of 20% or more of the non-display portion. A minimum distance is maintained between the stepped patterns and the pixel regions.

Display substrate and display device including the same

A display device includes a plurality of pixels, a data line transmitting a data voltage to the pixels, and a floating bar crossing the data line and being divided into a plurality of pieces. By dividing the floating bar into a plurality of pieces, a delay of a data signal can be prevented so that excellent images can be displayed. Furthermore, by disposing a diode between the pieces of the floating bar, an effect of dispersing static electricity can be maximized.
