Abstract
A polarizer component has an optical film to receive excitation light, a light re-emitting layer and a polarizing layer. The light re-emitting layer has quantum dots that re-emit red light and quantum dots that re-emit green light in response to the excitation light. The re-emitted red light is provided to a red sub-pixel to be filtered by a red color filter, and the re-emitting green light is provided to a green sub-pixel to be filtered by a green color filter. The excitation light can be blue or ultra violet and part of the excitation light is provided to a blue sub-pixel. The polarizing layer can be a reflective polarizing layer and the optical film can be a wavelength selecting layer. The light re-emitting layer may contain scattering particles to diffuse the excitation light provided to a blue sub-pixel.
