TECHNICAL FIELD

The present disclosure relates to the technical field of display technology, and in particular to a display panel, a method for manufacturing the same, and a display apparatus.

BACKGROUND

With the development of flexible display technology, display panels tend to be stretchable. A stretchable display panel includes a stretchable substrate, a stretchable thin film transistor (TFT), a stretchable package layer, and the like. In order to realize stretchability of the package layer, display structures on the substrate are packaged based on regions (e.g., packaged region by region) to separate the package layers for different regions from each other, so that the package structure can better adapt to the stress applied when the display panel is stretched.
