PROBLEM TO BE SOLVED: To make a display device small and lightweight which makes a user visually recognize a virtual image corresponding to a real image which is display on an image display surface in a farther distance than the actual image. SOLUTION: The display device is equipped with; an image display surface 2a which emits luminous fluxes for image display; and a micro-lens array 3 which is arranged along the image display surface 2a. Each lens 3a which constitutes the micro-lens array 3 deflects respective light beams constituting a luminous flux for image display which are emitted from an arbitrary one point in the image display surface 2a in directions to which mutual flatness becomes high at an image visually recognizing position.
