  • COMPOSITE FILM AND DISPLAY DEVICE COMPRISING SAME
    Publication number: 20230272175
    Abstract: In the composite film according to the embodiment, an elastic layer in which its modulus change characteristics with respect to temperature have been adjusted to a certain range is coated onto the opposite side to a hard coating layer; thus, it is possible to enhance the surface hardness and elastic recovery characteristics of the hard coating layer. Thus, it can be advantageously applied as a cover window of a flexible display device.
