1. A method for producing a display with a diffraction grating pattern, comprising the steps of:

  • reading image data;

    assigning a color for a light exposure range and moving a slit of an optical system to a position corresponding to said assigned color;

    moving an origin of an x-y stage and setting initial data of said assigned color;

    reading data of an assigned address of said image data and opening a shutter of said optical system for light exposure when data of said assigned color exists;

    moving said x-y stage to increase said address by one and repeating said data-reading and shutter-opening step until no further data within said light exposure color range exists; and

    changing said assigned color for a light exposure range and repeating the above sequence of steps until no further light exposure data exists.
