  9. A vehicle comprising: a vehicle body; and a display device (100) of any one of claims 1 to 8 provided in the vehicle body.
  10. The vehicle of claim 9, wherein the housing (2100) is an instrument panel (IP) of the vehicle body.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S) This application is based on and claims priority to Korean Patent Application No. 10-2023-0118371, which was filed in the Korean Intellectual Property Office on September 06, 2023. BACKGROUND 1. Field The present invention relates to a flexible display device and a vehicle equipped with the display device. 2. Description of Related Art A center fascia display of a vehicle may display various visual information about the vehicle. Such a display device may also be installed on a dashboard of a vehicle disposed in front of a driver's seat and a front passenger seat, and provides various convenience information such as navigation, vehicle management and operation, Internet, and entertainment. In this regard, there is a movable display device, and the movable display device is capable of moving up and down or left and right relative to a dashboard. As the display moves along a guide, a driver and a passenger may selectively use the display. In the case of a display in the form of a pop-up, the display may be stored and then extended and used when necessary. Since an installation position of a fixed display is fixed, the use of space in a vehicle is limited, and as a display size increases, the forward visibility decreases. A pop-up style movable display requires a separate accommodation space for the display, and as the size of the display increases, the size of the accommodation space also increases, limiting the utilization of space in the vehicle. In addition, since an entire screen is operated in an LCD screen display, inefficiency in that all power is used regardless of a degree of exposure of the display remains. US 2017/013726 A1 discloses a display device having a display winder configured to wind and unwind a display and a housing accommodating the display, the display having on the top a top case covering the display. DE 10 2005 052 030 A1 and DE 11 2014 001 802 B4 are related art. DE 10 2005 052 030 A1 discloses a display device having coupling means which induces a asymmetric coupling between movement of a display unit and movement of a cover. DE 11 2014 001 802 B4 discloses a display device for a vehicle in which a shutter having a compact configuration can close an opening on an upper surface of a bearing housing in order to insert and remove a reflection plate. Therefore, it is required to develop a display device having a form and structure for multiplying advantages while minimizing these disadvantages. SUMMARY An object of the invention is to provide a display device for reducing the size of an accommodation space of a display used in a vehicle. An object of the invention is to provide a display device for efficiently retracting or extending a display used in a vehicle from an accommodation space. An object of invention is to provide a display device for controlling a degree of exposure of a display according to a purpose of using a display. In addition, an object of the invention is to provide a display device for saving power for outputting a display image. It will be appreciated by one of ordinary skill in the art that the objects that could be achieved with the disclosure are not limited to what has been particularly described hereinabove and the above and other objects that the disclosure could achieve will be more clearly understood from the following detailed description. To achieve the above objects, a display device according to the invention includes a display driver moving a display, a display winder winding and unwinding the display according to the movement of the display, and a display support unit supporting the display. The display support unit includes a housing supporting the display, a door provided in the housing and movable to enable the display to move into and out of the housing, and a door driver moving the door. According to the invention the door driver may include a second motor providing a driving force, and a cam receiving the driving force and rotatable by the driving force, and the door may be linearly movable by rotation of the cam. According to the invention the door driver may further include a blocker fixed to the cam and upon rotation of the cam, rotating together with the cam, and a sensor including a light emitter emitting light and a light receiver receiving the light, and on/off of the sensor may be determined according to whether the light is blocked by the blocker. According to teh invention the cam may include a cam pulley connected to the second motor by a second timing belt and being a rotation axis of the cam. The cam may include a first surface formed in a straight line and a second surface formed in a curve with a decreasing curvature, and the cam pulley may be formed at a position where the first surface and the second surface meet. According to the invention the door may be in surface-contact with the second surface of the cam. According to the invention the door driver may include a slide unit to enable
