1. A combination structure, comprising
a nanostructure array including a plurality of nanostructures, each of the plurality of nanostructures having a width smaller than a near-infrared wavelength and are repeatedly arranged, and
a light absorption portion adjacent to the nanostructure array, the light absorption portion including a near-infrared absorbing material configured to selectively absorb light in at least a portion of a near-infrared wavelength region.
