PROBLEM TO BE SOLVED: To provide an X-ray waveguide which wave-guides an in-phase X-ray with high propagation efficiency by enhancing the confinement effect of a cladding.SOLUTION: The X-ray waveguide includes a core for wave-guiding the X-ray and a cladding. The core has a periodic structure containing a plurality of materials with different refraction factor real parts in a direction perpendicular to the waveguide direction of the X-ray. A flattening layer arranged between the core and the cladding. The core and the flattening layer come in contact with the cladding. A critical total reflection angle in interfaces between the cladding and the flattening layer and between the cladding and the core are larger than a Bragg angle caused by the periodicity of the core.

PROBLEM TO BE SOLVED: To form a light take-out structure that efficiently takes out light emitted from a light emission layer displaying an image by light emission.SOLUTION: A capture layer 16 is formed on a film 14 of a first optically transparent material provided on a substrate 11, and coated with a fluid dispersion having particles 17 dispersed in a dispersant 19, which is vaporized to form a sedimentary layer 17a of the particles 17 on the capture layer 16. The particles 17 of a bottom layer of the sedimentary layer 17a are captured in the capture layer 16 at a particle packing factor which is ≥93% of two-dimensional closest packing, the particles 17 which are not captured in the capture layer 16 are removed, and etching is carried out using the particles 17 captured in the capture layer 16 as a mask to form recesses in the film 14 of the first optically transparent material. After the particles 17 and the capture layer 16 which are left after the etching are removed, the recesses are filled with a second optically transparent material differing in a refractive index from the first optical transparent material.
