Title:
BODY HAVING FINE CONCAVITIES AND CONVEXITIES IN SURFACE, AND PRODUCTION METHOD OF BODY HAVING FINE CONCAVITIES AND CONVEXITIES IN SURFACE
Document Type and Number:
WIPO Patent Application WO/2014/148492
Kind Code:
A1
Abstract:
The present invention relates to a body in which fine concavities and convexities are formed in at least a part of the surface, characterized in that the fine concavities and convexities consist of a wave-shape concavo-convex pattern and multiple concavities or convexities formed on said wave-shape concavo-convex pattern; the wave-shape concavo-convex pattern consists of irregularly formed convex ridges and concave furrows between the convex ridges; the convex ridges meander non-parallel to one another; the modal pitch of the convex ridges is 3-20μm; and, the apparent modal diameter of the concavities or convexities is 1-10μm. By means of the present invention, it is possible to provide an easily produced body having fine concavities and convexities in the surface and a production method thereof, wherein, when used as a light diffuser, said body has to a certain extent a diffusion angle even in the direction perpendicular to the main diffusion direction while still maintaining the diffusion angle of the primary diffusion direction.
