Display panel and method of fabricating the same

A method of fabricating a display panel, wherein the display panel comprises a hole region and a display region surrounding the hole region, and the method comprises:

• forming a flexible substrate layer and a patterned barrier layer on a substrate, wherein the patterned barrier layer comprises a first annular opening surrounding the hole region;
• etching the flexible substrate layer under shielding of the patterned barrier layer to form a patterned flexible substrate layer, wherein the patterned flexible substrate layer comprises a first sacrificial portion formed in the hole region and a body portion formed in the display region, and a second annular opening is formed between the body portion and the first sacrificial portion;
• forming a device layer on a side of the patterned barrier layer away from the patterned flexible substrate layer to form a semi-finished product of the display panel, wherein the device layer comprises a display function portion located in the display region and a second sacrificial portion formed within the second annular opening and above the first sacrificial portion;
• stripping the substrate to remove the substrate together with the first sacrificial portion, the second sacrificial portion, and the patterned barrier layer corresponding to the hole region and above the substrate, wherein the first sacrificial portion, the second sacrificial portion, and the patterned barrier layer remain fixed to the substrate.
