Abstract: A window member according to an embodiment of the inventive concept includes a first base member having a first thickness, a first impact absorbing layer disposed on one surface of the first base member and having a storage modulus less than that of the first base member and a second thickness, a first hard coating layer disposed on the first impact absorbing layer, and a second hard coating layer disposed on the other surface that is opposite to the one surface of the first base member. Here, a ratio of the second thickness to the first thickness is equal to or greater than about 1.0 and equal to or less than about 1.67. The first base member is bent with respect to a bending axis extending in one direction.

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.

Abstract: A flexible display device including a hard coating layer, the hard coating layer containing first hard coating oligomers, second hard coating oligomers having greater molecular weights than the first hard coating oligomers, a cross-linker, and a photoinitiator. The first hard coating oligomers may maintain the hardness of the hard coating layer and the second hard coating oligomers may improve the flexibility of the hard coating layer, such that damage to the hard coating layer may be prevented or reduced even when the flexible display device is bent.
