1. A foldable display device, wherein the foldable display device comprises:
a display panel, wherein the display panel comprises a display region, a bonding region and a bending region, wherein the bending region is located between the display region and the bonding region;
a first adhering layer disposed on one side of the display panel, wherein the one side of the display panel is away from a light exiting side of the display panel; and
a supporting layer disposed on one side of the first adhering layer, wherein the one side of the first adhering layer is away from the display panel;
wherein orthographic projections of the supporting layer and the first adhering layer on the display panel are located within the display region; and
the first adhering layer comprises a first adhering part and a second adhering part, the first adhering part is disposed on one side of the second adhering part, wherein the one side of the second adhering part is away from the bending region, and an elasticity modulus of the second adhering part is greater than an elasticity modulus of the first adhering part;
wherein the bonding region is located on an opposite side of the light exiting side of the display panel;
the display panel comprises a panel body, a first back film and a second back film;
the panel body is distributed at the display region, the bonding region and the bending region;
the first back film is located within the display region, and is located between the panel body and the first adhering layer; and
the second back film is located within the bonding region, and is located on one side of the panel body, wherein the one side of the panel body faces the supporting layer.
