Abstract:
1. A method of producing a shaped article for use as an optical component comprising: a step of injecting into a cell a photopolymerizable composition containing a multifunctional monomer or oligomer comprising two or more functions and a photopolymerization initiator; and a step of directing parallel rays from a surface-emitting light source onto the photopolymerizable composition so polymerization of the photopolymerizable composition uniformly proceeds in a plane normal to a thickness direction of the photopolymerizable composition, thereby polymerization-curing the photopolymerizable composition to form a shaped article for use as an optical component composed of a matrix and numerous columnar structure bodies arrayed in one direction within the matrix, wherein the full width at half maximum of the parallel rays is not greater than 100 nm, the parallelism of the rays is such that the beam spread angle is not greater than +/−0.03 rad, and the wavelength of the rays is 250 to 400 nm.
