Claim 6:
7. A flexible display device, comprising a flexible display panel and a back supporting film bound to a back surface of the flexible display panel, wherein the flexible display panel comprises a bonding region and a non-bonding region, wherein
the back supporting film comprises: a first base material layer bound to the flexible display panel in at least a portion of the bonding region, and a second base material layer bound to the flexible display panel in at least a portion of the non-bonding region,
wherein the first base material layer is bound to the flexible display panel via a transparent first adhesive layer, the first base material layer has a transmittance of 85% or more and a haze of 5% or less,
wherein the second base material layer is bound to the flexible display panel via a second adhesive layer, wherein the second base material is different from the first base material,
wherein the second base material has an elastic modulus and/or a breaking strength greater than those of the first base material, and
wherein the first adhesive has an elastic modulus greater than that of the second adhesive.
