Abstract: The present invention provides a functional film having an optical functional layer that exhibits an optical function and is capable of suppressing deterioration of the optical functional layer, and a method thereof. The functional film includes an optical functional layer, a resin layer which surrounds end surfaces of the optical functional layer, and gas barrier supports between which the optical functional layer and the resin layer are sandwiched, in which an oxygen permeability of the resin layer is 10 cc/(m2·day·atm) or less, and a difference between a thickness of the optical functional layer and the resin layer is within 30%; and a production method including forming a frame-shaped resin layer on a surface of a first gas barrier support, filling the inside of the frame with a polymerizable composition which becomes an optical functional layer, laminating a second gas barrier support on the resin layer, and curing the polymerizable composition.

Abstract: A plant growth lighting fixture has two or more of a blue light source, a green light source, and a red light source and a reflective-type circularly polarizing plate having two or more of a blue-reflecting cholesteric liquid crystal layer having a center wavelength of an effective wavelength range in blue light, a green-reflecting cholesteric liquid crystal layer having a center wavelength of an effective wavelength range in green light, and a red-reflecting cholesteric liquid crystal layer having a center wavelength of an effective wavelength range in red light. The wavelength ranges of the emission center wavelengths as the light sources and the wavelength ranges of the center wavelength of the effective wavelength range as the reflective-type circularly polarizing plate are wavelength ranges of the same colors, and the reflective-type circularly polarizing plate has a polarization correction layer having a phase difference in a thickness direction.
