FILLER LENS AND ITS MANUFACTURING METHOD

摘要

A filler lens exhibiting an enough light diffusing ability to diffuse both the light incident on the film side and the light incident on the filler side and having a light transmittance better than those of conventional light diffusers having multiple filler layers and a method for manufacturing the same are disclosed. The filler lens comprises a base sheet (1), a bonding layer (2) formed on the base sheet (1) directly on the base sheet (1) or on another layer formed on the base sheet (1), and a filler layer (3A) embedded in the surface layer of the bonding layer (2), with a part of the filler layer (3A) projecting from the surface of the bonding layer (2). In the filler layer (3A), fillers (3) are densely arranged and form a single layer, and part of each of the fillers (3) projects from the surface of the bonding layer (2).
