  • DIFFRACTION GRATING, ORGANIC EL ELEMENT USING THE SAME, AND MANUFACTURING METHODS THEREOF
    Publication number: 20120132897
    Abstract: A diffraction grating having a transparent supporting substrate; and a cured resin layer which is stacked on the transparent supporting substrate and which has concavities and convexities formed on a surface thereof, wherein when a Fourier-transformed image is obtained by performing two-dimensional fast Fourier transform processing on a concavity and convexity analysis image obtained by analyzing a shape of the concavities and convexities formed on the surface of the cured resin layer by use of an atomic force microscope, the Fourier-transformed image shows a circular or annular pattern substantially centered at an origin at which an absolute value of wavenumber is 0 ?m?1, and the circular or annular pattern is present within a region where an absolute value of wavenumber is within a range of 10 ?m?1 or less.
