The constituent material of person can be the same or different from each other, and can be high molecular material or metal, and wherein high molecular material is for example
It is polypropylene (Polypropylene, PP) or polyethylene (Polyethylene, PE), but not limited to this.Bearing bed 123 and
One supporting layer 124a is both connected to these un-flexed portion 120b, and bearing bed 123 and the first supporting layer 124a face each other ground
Separate, so as to form the first hollow space H11 between bearing bed 123 and the first supporting layer 124a.
Bearing bed 123 has outer surface S11 and inner surface S12, and wherein outer surface S11 is relative to inner surface
S12.Flexible display panels 110 are fixed on outer surface S11, and cover bendable portion 120a and these un-flexed portion 120b,
And the first hollow space H11 is formed between the first supporting layer 124a and inner surface S12.Bearing bed 123 can also have at least
One protrudes from the convex block 123b of inner surface S12.By taking Figure 1A and Figure 1B as an example, convex block 123b possessed by bearing bed 123
Quantity is three, and wherein these convex blocks 123b all extends along axis A11, therefore these convex blocks 123b is alongside one another.In addition, palpus

Second supporting layer 125b can also be flexible film layer, can have multiple warpages, such as the first supporting layer 124a,
And deformation 125r is curved film layer.The thickness 125t of second supporting layer 125b is less than the thickness of each un-flexed portion 120b
120t.By taking Figure 1A as an example, thickness 125t is maximum of the second supporting layer 125b when flexible display 100 shakeouts and is not bent
Thickness, i.e. thickness 125t are equivalent to the bottom end deformation 125r the distance between to supporting surface 125s.Due to the second supporting layer 125b
Thickness 125t be less than the thickness 120t of un-flexed portion 120b, therefore the second supporting layer 125b can also form hinge living.
When flexible display 100 is bent along axis A11, the second supporting layer 125b also can with bending, wherein
The supporting surface 125s of second supporting layer 125b contacts the first supporting layer 124a, and the recessed rib 124r contact second of deformation deformed supports
