Claim 6:
7. A method for preparing a display panel, comprising:
providing a substrate;
forming a metal wiring layer on a non-display area of the substrate, the metal wiring layer comprising a plurality of metal wirings;
forming a planarization layer on the non-display area of the substrate and the metal wiring layer;
processing the planarization layer to form a plurality of grooves corresponding to the plurality of metal wirings, the grooves each being located on a side, facing away from the substrate, of a metal wiring corresponding to the each groove and exposing the metal wiring; and
