摘要：The present invention provides an optical sheet that excels in a light
convergence function or a light diffusion function, has excellent brightness increase ratio
in the desired angular direction, in particular the front surface direction, and greatlyinhibits the side lobe, and a method for manufacturing such an optical sheet with goodefficiency and high accuracy. The optical sheet has a substrate that has a first surfacehaving formed thereon a peak-valley portion that converges and scatters light and anoptical adjustment portion that differs in an optical property from the substrate. Aplurality of the optical adjustment portions are formed at least in part of a non-passageportion for the light in the substrate in the case where a parallel beam falls from the firstsurface in a direction normal to a surface located opposite the first surface.
