Foldable display panel and foldable display device

The embodiment of the utility model provides a foldable display panel and a foldable display device, relates to the technical field of display, and is used for improving the definition of photographing and imaging. The foldable display panel comprises a display area and a light-transmitting area. The foldable display panel further comprises a display substrate, a transparent cover plate, a first buffer layer, a first protective layer and a first shading layer. The transparent cover plate is located on the light emitting side of the display substrate. The first buffer layer is located between the transparent cover plate and the display substrate. The first protection layer is located on the side, away from the first buffer layer, of the transparent cover plate, and the elasticity modulus of the first protection layer is larger than that of the first buffer layer. The first shading layer is located between the transparent cover plate and the display substrate. The first shading layer surrounds at least part of the light-transmitting area, the first shading layer comprises a first opening area, and the orthographic projection of the light-transmitting area on the transparent cover plate is at least partially overlapped with the orthographic projection of the first opening area on the transparent cover plate. The foldable display panel is used for displaying images.
