IMAGE DISPLAY DEVICE USING DIFFRACTIVE LENS

摘要

PROBLEM TO BE SOLVED: To provide an image display device which is easily mass-produced.SOLUTION: An image display device using a diffractive lens is provided. The image display device includes a display panel that displays an image, and a diffractive lens for the image of the display panel to be recognized as a two-dimensional image or a three-dimensional image, where the diffractive lens modifies a path of light by using an optical principle of a Fresnel zone plate.SELECTED DRAWING: Figure 6
