Abstract:
A composition for a window film includes a siloxane resin represented by Formula 1, and an initiator. A flexible window film is manufactured using the same, and has a pencil hardness of about 7H or higher, a radius of curvature of about 5.0 mm or lower, and a difference in yellow index before and after irradiation (ΔY.I.) of about 5.0 or less. A flexible display includes the flexible window film. (R1SiO3/2)x(R2R3SiO2/2)y Formula 1
