Abstract
A display includes a plurality of blue, green, and red light emitting elements having respective blue, green, and red emission spectra including respective blue, green, and red emission peaks at respective blue, green, and red peak wavelengths with respective blue, green, and red full width at half maxima (FWHMs). The display includes a display panel and an optically collimating film. For a substantially collimated incident light and for each of mutually orthogonal polarization states, an optical transmittance of the optically collimating film includes substantially distinct blue, green, and red transmission bands having respective blue, green, and red FWHMs that overlap at least 30% of the respective blue, green, and red FWHMs at a first incident angle of less than about 10 degrees and overlap less than 15% of the respective blue, green, and red FWHMs at a second incident angle of greater than about 30 degrees.
