A single-lens-reflex digital camera in which an optical image of an object that is to be photographed via a photographing lens is reflected by a main mirror to be formed on a focusing screen so that the optical image is viewed through a viewfinder while the main mirror is retracted from an optical path of the photographing lens to capture an image of the object by an image pickup device, the single-lens-reflex digital camera includes an electroluminescent display provided on the focusing screen, wherein the electroluminescent display displays at least the object image captured by the image pickup device. The single-lens-reflex digital camera is configured to allow the object image displayed by the electroluminescent display and the optical image formed on the focusing screen to be viewed through the viewfinder.
