Abstract: The present disclosure discloses a wearable display device which includes a flexible screen and a support component supporting the flexible screen. The flexible screen includes a fixed region and a movable region. The support component includes a fixing portion fixedly connected with the fixed region and a movable support plate fixedly connected with the movable region. The movable support plate is hinged with the fixing portion, and the movable support plate drives the movable region to rotate to a preset angle relative to the fixing portion. The technical solution of the present application can make the display screen of the wearable display device be a foldable display screen, and specifically, the user can fold the flexible screen to adjust the display direction of the flexible screen, so as to enrich the use range and use functions of the wearable display device.
