By providing the opening K at the position of the support film 6 corresponding to the bending region C, the bending characteristics of the portion of the substrate 1 located in the bending region C can be improved. Meanwhile, the support part 7 is arranged at the position where the part of the support film 6 located in the display area a and the part located in the binding area B correspond to the opening K, so that the part of the substrate 1 located in the bending area C is supported, and the first extension part 11 can extend in the direction perpendicular to the plane of the display layer 3.
