Claim 13:
14. The method of claim 13, further comprising:
providing a support substrate;
forming a debonding layer limited in the display-bonding sub-area, and in a region corresponding to the bonding pad;
forming the bonding pad on a side of the debonding layer away from the support substrate;
forming an insulating material layer limited in the display-bonding sub-area;
forming a base substrate material layer throughout the regular display sub-area and the display-bonding sub-area, and on a side of the insulating material layer away from the support substrate; and
etching the insulating material layer and the base substrate material layer to form the via extending through the insulating material layer and the base substrate material layer to expose a contacting surface of the bonding pad, thereby forming an insulating layer limited in the display-bonding sub-area, and the base substrate on the insulating layer.
