Abstract

See full text

A method of manufacturing a display having diffraction grating patterns, includes the steps of (a) obtaining a plurality of two-dimensional images by observing an object at a plurality of positions, and inputting images of the plurality of two-dimensional images in a computer, (b) selecting nth image data from the plurality of image data, (c) inputting data of a reproducing light source position and a view direction, (d) inputting predetermined dot data of the nth image data, (e) determining a pitch and a direction of a grating and an area of a dot on the basis of the data of the reproducing light source position and the view direction and the dot data, (f) moving an X-Y stage to a predetermined position on the basis of the dot data and delineating the diffraction grating by using an electron scanning unit, (g) sequentially incrementing an address of the dot data and repeating the steps (d) to (f) until all data corresponding to the nth image data are processed, and (h) selecting another image data, and repeating the steps (b) to (g) until all image data are processed.
