The method includes the steps of: forming a lens-shaped curve at a surface side of a transparent substrate; forming an inorganic material film on the transparent substrate so as to bury the curve therewith; and planarizing the surface of the inorganic material film to provide a microlens where the curve is buried with the inorganic material film. The image display method involves operating a computer having a display screen, a memory and a processing unit for simulating the motion of objects and displaying the results on the display screen.
