Abstract: Disclosed is a wavelength conversion film including at least two or more dyes and absorbing irradiation light to emit light at a longer wavelength than that of the irradiation light. The wavelength conversion film includes a first dye having a maximum absorption wavelength in a red light region, and a second dye absorbing excitation energy of the first dye to emit light in a near infrared region.
