Antireflective grating in the resonance domain for displays.
An antireflective periodic structure different from the moth-eye structure is proposed in a resonance domain whose period is greater than the wavelength of incident light. Using rigorous coupled-wave analysis in the TE mode, a reflectivity of less than 0.2% is performed in a period larger than the wavelength, when an aspect ratio is unity. Changes in diffraction efficiency and transmissivity are small at different wavelengths. This is explained by a newly derived equation based on the vector theory.
