Abstract

A method for producing an at least partially transparent optical component including a laminate including fabricating a precursor laminate by bonding a transparent substrate and a transparent film to each other with a transparent photocurable adhesive layer interposed therebetween; curing the transparent photocurable adhesive layer by applying light thereto to change the precursor laminate into the laminate thereby, such that a shear modulus G' of the transparent photocurable adhesive layer of the laminate measured under a condition of a temperature of 25° C. and a frequency of 1 Hz reaches a value within a range of 3×10Pa≤G′≤3×10Pa; and forming a flush and surface of the laminate by cutting the laminate in a thickness direction, such that the flush end surface includes respective cut surfaces of the transparent film, the transparent photocurable adhesive layer, and the transparent substrate.
