Abstract:
An optical device comprising:a light transmittable base; and a device constituent layer provided on said base; wherein said base includes, at least in a pixel formation region, continuously extending layers arranged to exhibit a cyclic refractive index distribution in the in-plane direction and to exhibit a specific refractive index in the thickness direction; wherein said base, on the device constituent layer side, has a surface roughness of 300 nm or less; wherein said base comprises a plurality of pixel formation regions, each having an aggregation of truncated optical fibers arranged in such a manner as to extend along the thickness direction of said base; each truncated optical fiber in said aggregation of truncated optical fibers having a first end surface and a second end surface on opposing ends of the optical fiber; said first end surface having a greater area than said second end surface; wherein a center-to-center distance between adjacent first end surfaces is greater than a center-to-center distance between adjacent second end surfaces.
