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.
