<p>An image display unit or the like capable of displaying a high-precision image at a wide view of angle. A display device (603) is disposed on the concave lens side of a micro-lens array (710) having many minute inversed Galilean type telescopes, consisting of minute convex lenses and minute concave lenses, arranged in parallel two-dimensionally and an observing position is set on the convex lens side thereof, and the optical axes of convex lenses and those of concave lenses of the inversed Galilean type telescope units are gradually off-centered from one another from the center toward the peripheral of the micro-lens array, whereby the correspondingly identical portions of respective virtual images of the display device remotely formed by respective inversed Galilean type telescopes overlappingly agree to one another at the same position and with the same size to thereby synthesize one virtual image corresponding to the display device by the entire micro-lens array.</p> |
