More Information
Summary:A diffraction grating structure, an augmented reality apparatus including the same, and a method of manufacturing the diffraction grating structure are provided. The diffraction grating structure includes first and second substrates spaced apart from each other, a photodirector layer arranged between the first and second substrates and including an interference pattern formed therein, and a liquid crystal layer arranged on the photodirector layer and including liquid crystals oriented to correspond to the interference pattern and liquid crystals arranged in a chaotic state. Thus, an augmented reality apparatus having a large viewing angle due to the above diffraction grating structure may be implemented.
