Claim:
1. A flexible display device comprising: a display screen, wherein a side of the display screen for image display is a display side, and wherein a side opposite to the display side is a back side; a plurality of limiting structures arranged at the back side of the display screen, wherein each limiting structure comprises a bottom end, a head end and a tail end; wherein an end surface of the bottom end of each limiting structure is fixed on the back side of the display screen; wherein the head end of each limiting structure has a protrusion, the protrusion comprising a first abutting surface and a second abutting surface adjoined with each other, an opening of an angle between the first abutting surface and the second abutting surface faces away from the display screen; wherein the tail end of each limiting structure has a groove, the groove comprising a third abutting surface and a fourth abutting surface adjoined with each other, an opening of an angle between the third abutting surface and the fourth abutting surface faces away from the display screen, and the angle between the third abutting surface and the fourth abutting surface is larger than the angle between the first abutting surface and the second abutting surface; wherein the plurality of limiting structures are arranged in at least one row, a protrusion of a latter limiting structure in one row is located in a groove of a previous limiting structure, and the first abutting surface of the latter limiting structure is opposite to the third abutting surface of the previous limiting structure, and the second abutting surface of the latter limiting structure is opposite to the fourth abutting surface of the previous limiting structure; wherein when the flexible display device bends towards the back side to a first curvature, the first abutting surface of the latter limiting structure and the third abutting surface of the previous limiting structure abut against each other; and wherein when the flexible display device bends towards the display side to a second curvature, the second abutting surface of the latter limiting structure and the fourth abutting surface of the previous limiting structure abut against each other.
