PROBLEM TO BE SOLVED: To provide a display device capable of displaying a stereoscopic two-dimensional video corresponding to an information holder arranged around an imaging optical element with rich presence at a proper timing above the device.SOLUTION: The display device includes an imaging optical element (miro-mirror array M) which is disposed on the upper surface of a housing, so as to have a light transmission shape, a display D which is disposed to be inclined by a predetermined angle to the lower surface of the imaging optical element, a reader R which reads information possessed by an information holder (card C) in a non-contact state, a sensor S which detects the presence or absence of an object on the upper surface of the housing, and control means which controls the display of the display. The control means prepares an image I corresponding to the information holder on the basis of the information of the image holder transmitted from the reader R and displays the prepared image I as a spatial image I' at an excellent timing on the basis of an object detection signal transmitted from the sensor S. |
