Abstract: A combination structure includes an in-plane pattern of unit cells, wherein the each unit cell includes nanostructures each having a dimension that is smaller than a near-infrared wavelength and a light-absorbing layer adjacent to the nanostructures and including a near-infrared absorbing material configured to absorb light in at least a portion of a near-infrared wavelength spectrum. The nanostructures are define a nanostructure array in the unit cells, and a wavelength width at 50% transmittance of a transmission spectrum in the near-infrared wavelength spectrum of the combination structure is wider than a wavelength width at 50% transmittance of a transmission spectrum in the near-infrared wavelength spectrum of the nanostructure array.
