A filler lens which yields sufficient light diffusivity in both the cases in which light is transmitted from the film side and in which it is transmitted from the filler side and which has a light transmittance superior to that of conventional light diffusing members in which a filler layer is formed as a multilayer, and a production method therefor are disclosed. The filler lens comprises a sheet-shaped base material (1), a binding layer (2) provided on this base material (1) directly or via another layer, and a filler layer (3A) embedded in the surface of the binding layer (2). In the filler layer (3A), the fillers (3) form a monolayer at a high density and part of the filler (3) protrudes from the surface of the binding layer (2).
A production method for a filler lens, the filler lens comprising a base material, a binding layer provided on said base material directly or via another layer, and a filler layer consisting of plural fillers embedded in the surface of said binding layer so that part of said filler protrudes from the surface thereof, the method comprising:
A production method for a filler lens, the filler lens comprising a base material, a binding layer provided on said base material directly or via another layer, and a filler layer consisting of plural fillers embedded in the surface of said binding layer so that part of said filler protrudes from the surface thereof, wherein said binding layer has a gel percentage of 60% or more, and a protruding ratio of said filler is 50% or more, the method comprising:
A production method for a filler lens, the filler lens comprising a base material, a binding layer provided on said base material directly or via another layer, and a filler layer consisting of plural fillers embedded in the surface of said binding layer so that part of said filler protrudes from the surface thereof, wherein an elevated portion of said binding layer is provided around said filler, the method comprising:
A production method for a filler lens, a filler lens comprising a base material, a binding layer provided on said base material directly or via another layer, and a filler layer consisting of plural fillers embedded in the surface of said binding layer so that part of said filler protrudes from the surface thereof, wherein said binding layer is cured by a cure-controlled hardener, the method comprising:
