Abstract: The present invention relates to an optical device that is capable of producing an image in the air, which includes a substrate having a reflective diffraction region formed into a net structure, and a light radiation unit which radiates a light beam onto one surface of the substrate. The diffraction region is capable of collecting light beams that are diffracted in the upper space of one surface of the substrate by diffracting the light beam which is incident on one surface of the substrate. Here, the light radiation unit may have a display source that generates the light beams which form the image, and a lens portion that radiates the generated light beams onto the substrate.
