Claim 17:
18. A method of manufacturing a display substrate, the display substrate being the display substrate according to claim 1, the method comprising:
providing a rigid carrier; and
forming a flexible base on the rigid carrier, including:
forming an amorphous silicon layer to be processed, wherein the amorphous silicon layer to be processed includes the first portion located in the isolation area, the second portion located in the display area and a third portion located in the opening area, thicknesses of the first portion and the third portion are both greater than the thickness of the second portion;
scanning a surface of the rigid carrier away from the amorphous silicon layer to be processed once through a laser to separate the flexible base from the rigid carrier; and
removing the third portion to form the amorphous silicon layer.
