The present application discloses a display apparatus comprising a flexible display panel capable of undergoing deformation between a flat configuration in which the flexible display panel is substantially flat and a curved configuration in which the flexible display panel is curved; and a first arm section and a second arm section for deforming the flexible display panel between the flat configuration and the curved configuration. Each of the first arm section and the second arm section comprises a first terminal and a second terminal, the first terminal of the first arm section and the first terminal of the second arm section coupled to each other, and the second terminal of the first arm section and the second terminal of the second arm section coupled to the flexible display panel on a side distal to a light emitting surface of the flexible display panel and at two opposite margins of the flexible display panel, respectively; the first arm section is a retractable arm section capable of retracting and extending between the first terminal and the second terminal of the first arm section, having an extended state corresponding to the flexible display panel in a flat configuration and a retracted state corresponding to the flexible display panel in a curved configuration; and the second arm section is a retractable arm section capable of retracting and extending between the first terminal and the second terminal of the second arm section, having an extended state corresponding to the flexible display panel in the flat configuration and a retracted state corresponding to the flexible display panel in the curved configuration.
