1. A method of manufacturing a cured product, the method comprising:
a first light irradiation step of irradiating a resin composition comprising an oligomer comprising a silicon (Si)-containing functional group; an oligomer comprising a fluorine (F)-containing functional group; and an acrylic oligomer with light having a wavelength of 300 nm or less to activate a resin composition;
a second light irradiation step of irradiating the activated resin composition with light having a wavelength of 700 nm or higher to thermally cure the resin composition; and
a third light irradiation step of irradiating the thermally cured resin composition with light having a wavelength of 400 nm or less to optically cure the resin composition.
