CROSS-REFERENCE TO RELATED APPLICATIONS 
     Pursuant to 35 U.S.C. § 119 (a), this application claims the benefit of an earlier filing date and right of priority to International Application No. PCT/KR2021/000086, filed on Jan.5, 2021, the contents of which is hereby incorporated by reference herein in its entirety. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the invention 
     The present disclosure relates to a control box and a display device including the same. 
     2. Description of the Related Art 
     With the advent of the information society, various demands for display devices are increasing. Various display devices, such as liquid crystal display (LCD) devices, plasma display panel (PDP) devices, electroluminescent display (ELD) devices, vacuum fluorescent display (VFD) devices, and organic light-emitting diode (OLED) devices, have been recently studied and used in response to various demands for display devices. 
     Thereamong, a display device using an organic light-emitting diode (OLED) is advantageous in that it has better luminance characteristics and viewing angle characteristics than a liquid crystal display device, and has an ultra-thin profile because it does not require a backlight unit, unlike the liquid crystal display device. 
     A control box may be positioned so as to be spaced apart from a display device and adjacent to a user so as to be used by the user. The control box may provide various pieces of information to the display device. For example, the control box may be an AV box. The control box may exchange information with a display head, which is provided with a display panel displaying an image, in a wired/wireless manner. 
     Recently, various studies have been conducted on the connectivity of such a display device.

     It is still another object of the present disclosure to provide a mechanism capable of improving the reception rate of an antenna of a wireless control box. 
     It is still another object of the present disclosure to provide a structure capable of effectively dissipating the heat generated in a wireless control box. 
     In order to accomplish the above and other objects, a control box according to one aspect of the present disclosure may include a case providing an inner accommodation space and having an opening formed in the upper surface thereof, a first plate supported by the lower surface of the case, a second plate located on the first plate so as to be spaced apart from the first plate, a third plate located on the second plate so as to be spaced apart from the second plate, a rotary plate covering the opening in the case and rotatably mounted to the third plate, and a transceiver located inside the case and coupled to the rotary plate.

An airflow path may be created between the upper surface of the housing  242  and the upper plate  2032  of the rotary plate  203  due to the pressure difference generated by the strong discharge of air through the outlet  244  of the fan  240 . 
     A discharge guide  260  may be disposed on the outer periphery of the outlet  244  of the fan  240 .
