Abstract

The foldable display device is provided with a display panel, a first adhering layer and a supporting layer, the first adhering layer includes a first adhering part and a second adhering part, the first adhering part is disposed on one side of the second adhering part. 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. The elasticity modulus of the second adhering part, which is close to the bending region, is set to be greater than the elasticity modulus of the first adhering part, which is away from the bending region. When the foldable display device is in the folding state, the supporting layer may appear staggered floor in the direction opposite to the bending region of the display panel to a larger extent.
