  • Patent number: 11594710
    Abstract: A method for manufacturing a display device that can prevent deformation of a flexible display is provided. A raw material sheet that serves as a metal sheet of the flexible display has a width that is greater than a width of the display body in Y direction and a plurality of holes are provided in a bent area of the raw material sheet over an entire width along a bent section of the display body. The method includes: mounting the display body on the raw material sheet such that the bent section and the bent area are aligned and that the display body avoids the end portions in the Y direction; applying pressure to the display body from a central part of the display body toward a periphery of the display body; and cutting the raw material sheet into a predetermined size.
