Abstract
The disclosure provides a back film structure, a method for manufacturing the back film structure, a display panel and a display device. The back film structure is divided into a bending region and a non-bending region. The back film structure includes a thin film layer and a barrier structure on a side of the thin film layer. An orthographic projection of the barrier structure on the thin film layer at least overlaps an orthographic projection of a boundary line between the bending region and the non-bending region on the thin film layer.
