1. A polarizer component comprising:

  • a polarizing layer;

    an optical film configured to receive an excitation light; and

    a light re-emitting layer disposed between the polarizing layer and the optical film, wherein the light re-emitting layer comprises a plurality of light re-emitting cells, each cell comprising at least a first sub-cell, a second sub-cell and a third sub-cell, the first sub-cell comprising a first light re-emitting material configured to emit a first light component in a first wave-length range in response to the excitation light, the second sub-cell comprising a second light re-emitting material configured to emit a second light component in a second wave-length range in response to the excitation light, the third sub-cell configured to provide a third light component in response to the excitation light, the first re-emitting material comprising a first quantum dot material arranged to emit the first light component, the second re-emitting material comprising a second quantum dot material arranged to emit the second light component, wherein the excitation light comprises a third wavelength range, wherein the optical film and the light re-emitting layer are arranged such that the excitation light is provided to the light re-emitting layer through the optical film, and wherein the optical film comprises a wavelength selecting layer configured to reflect light in the first wavelength range and light in the second wavelength range and to transmit light in the third wavelength range.
