Abstract: An optical construction is described that includes a blue light source, a liquid crystal display panel, and a quantum dot film element optically between the blue light source and the liquid crystal display panel. In some embodiments, the blue light source can emit blue light that has a wavelength in a range from 440 to 460 nm and an FWHM of less than 25 nm. Also, in some embodiments, the quantum dot film element includes a plurality of quantum dots emitting a peak red wavelength in a range from 600 to 640 nm, an FWHM of less than 50 nm, a peak green wavelength in a range from 515 to 555 nm, and an FWHM of less than 40 nm. The quantum dot film element can be optically between the blue light source and the LCD panel.
