Microlens array, a method for making a transfer master pattern for microlens array, a concave and convex pattern obtained from the transfer master pattern, a laminate for transfer, a diffuse reflection plate and a liquid crystal display device

A component, comprising a part having a concave and convex configuration for enabling at least one of light convergence, light diffusion and light diffraction, being formed as a reflective film, wherein a master pattern of said concave and convex configuration is formed by moving a cutting tool, which has a tip of a nose profile of radius R2 in which a half-moon shape nose profile is excised so that the tip is divided into parts by a straight line at the center part of the tip and one of the parts is excised, relative to a material along a tool moving locus of radius R1 that is so controlled on a processing device, said concave and convex configuration is transfer processed from said master pattern, and an outline of said concave and convex configuration viewed from a right angle relative to a horizontal face has a half moon-shape.
