     DETAILED DESCRIPTION 
     Hereinafter, a dish having a display element installed therein, and a charging device thereof, will be described in detail with reference to the drawings. Embodiments of the present invention may, however, be embodied in many different forms, and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, same reference numerals will be used throughout to designate same or like components. 
     In addition, unless explicitly described to the contrary, the word “comprise” and variations such as “comprises” or “comprising”, will be understood to imply the inclusion of stated elements but not the exclusion of other elements. It will be understood that when an element such as a layer, film, region, or plate is referred to as being “on” another element, it can be directly on the other element, or one or more intervening elements may be present. 
       FIG. 1  is a perspective view of a dish having a display element installed therein, and  FIG. 2  is an exploded perspective view of the dish having the display element installed therein, according to an exemplary embodiment of the present invention. 
     Referring to the drawings, the present embodiment includes a dish having a display element installed therein  10 , a dish main body  100 , a display element  110  ( FIG. 3 ), and a battery portion  120 . 
     The dish main body  100  is formed in the shape of a plate so that food can be put on an upper side thereof. The dish main body  100  is in the shape of a circular plate in the present exemplary embodiment, but may be formed in other shapes, such as the shape of a polygon like a triangle or a square, or may be a curved plate having the shape of, for example, a leaf or a water droplet. In addition, the upper side of the dish main body  100  may be flat or concave downward. As shown in  FIG. 2 , the dish main body  100  may include a center area  100   a  where food may be placed, and a periphery area  100   b  that is higher than the center area  100   a  (e.g., uplifted from, or rising from, the center area  100   a ) while surrounding the center area  100   a . Since the peripheral area  100   b  is higher than the center area  100   a , food can be prevented from moving outside of the dish main body  100 . Since the display element  110  is installed in the dish main body  100  to display an image or emit light, the upper side of the dish main body  100  may be at least partially formed of a transparent material. 
     The dish main body  100  may further include a protection film  140  covering the upper side of the dish main body  100 , and capable of being detached from the dish main body  100 . The protection film  140  can prevent, or reduce the likelihood of, an image displayed in the display element  110  from being unclear due to scratches caused by a fork or a knife, or scratches in the dish main body  100  resulting from washing. Since the protection film  140  is attachable/detachable, the protection film  140  may be attached during meal time, and the protection film  140  may be detached when the dish  10  is used for ornamental purposes. In addition, when scratches are generated in the protection film  140 , the scratched protection film  140  can be replaced with another protection film  140 . The protection film  140  may be a film used for surface protection, such as polyethylene terephthalate (PET) or polyethylene, although the present invention is not restricted to these materials.
