Display panel and fabrication method thereof, and display apparatus

A display apparatus, comprising:

• a display panel, comprising:
• a substrate;
• a drive substrate on the substrate, wherein the drive substrate includes a first film layer;
• and the first film layer includes a first opening;
• and
• a light-emitting element on the drive substrate, wherein the light-emitting element is disposed corresponding to the first opening, wherein:
• the drive substrate further includes an auxiliary film layer;
• and the auxiliary film layer includes a thickened part, a thinned part, or a hollow part overlapped with the first opening, and
• the drive substrate further includes a connection part disposed between the first film layer and the substrate and electrically connected to a thin film transistor, wherein the first opening exposes at least a first portion of the connection part and the first film layer covers at least a second portion of the connection part.
