  • Patent number: 11096274
    Abstract: A flexible display device includes a flexible display panel, a flexible printed circuit board extending from the display panel, an integrated circuit chip that is mounted on at least one surface of the flexible printed circuit board and is configured to drive the display panel, and a protection member attached to a rear surface of the display panel. When the flexible printed circuit board is flexed to be partially positioned on the rear surface of the display panel, the protection member is positioned between the display panel and the integrated circuit chip. The flexible display device prevents the integrated circuit chip stacked with the display panel from making direct contact with the display panel using the protection member. Thus, even if the display device is deformed into, for example, a flexed or rolled state, it is possible to prevent the display panel from being damaged.
