DISPLAY SUBSTRATE, METHOD OF MANUFACTURING THE SAME AND DISPLAY DEVICE HAVING THE SAME

摘要

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.

主权项

1. A display device having a display area and one or more peripheral areas and comprising:
a pixel transistor disposed in the display area; an integrated driving circuit disposed in at least one of the peripheral areas, the integrated driving circuit comprising a circuit part, a first wiring part extending in a first direction and electrically connected to the circuit part, and a second wiring part extending in a second direction to cross the first wiring part and electrically connected to the circuit part, where the second wiring part is disposed above the first wiring part; an insulation layer disposed on the first wiring part so as to electrically separate the first wiring part from the second wiring part; a protection layer disposed on the second wiring part; and a buffer layer disposed over the protection layer at least where the second wiring part crosses the first wiring part, the buffer layer comprising a light-blocking material; and a liquid crystal layer disposed on the integrated driving circuit and the pixel transistor.
