Abstract
A flexible display device includes a hard coating layer, the hard coating layer including hard coating oligomers, cross-linking oligomers that couple the hard coating oligomers, and a photoinitiator, the cross-linking oligomers being synthesized by catalytically reacting cross-linking monomers. The hard coating layer may include long cross-linking oligomers that improve the flexibility of the hard coating layer, and damage to the hard coating layer may be prevented or reduced even when the flexible display device is bent.
