Display panel and method for manufacturing the same, and display apparatus

A method for manufacturing a display panel, the method comprising:

• forming a flexible base on a substrate;
• forming a circuit layer on the flexible base, wherein the circuit layer is configured to be bonded to an external circuit structure;
• forming an insulating layer covering the circuit layer, wherein the insulating layer includes a barrier layer, a butter layer, a first gate insulating layer, a second gate insulating layer, and an interlayer dielectric layer that are sequentially stacked on the circuit layer, and the insulating layer has at least one via exposing the circuit layer;
• and
• forming a conductive layer on the insulating layer, wherein the conductive layer is electrically connected to the circuit layer through the at least one via, and the conductive layer is configured such that electrical signals lire transmitted between the conductive layer and the circuit layer;
• and
• after forming the circuit layer on the flexible base, the method further comprises:
• forming at least one opening in the flexible base, the at least one opening exposing at least partial region of the circuit layer.
