1. A display, comprising:
a plurality of light-emitting elements configured to emit a first light associated with a first predetermined wavelength band; and
an optical assembly including a reflective polarizer, a color conversion layer, and a color filter layer, the optical assembly configured to at least partially convert the first light associated with the first predetermined wavelength band into a second light associated with a second predetermined wavelength band, the second light being a polarized light of a predetermined polarization,
wherein the reflective polarizer is configured to selectively reflect or transmit a light depending on a polarization of the light when the light is associated with the first predetermined wavelength band, and transmit the light independent of the polarization of the light when the light is associated with a wavelength band outside of the first predetermined wavelength band.
