Abstract: The present disclosure describes an optical stack that includes an asymmetric diffuser. As described herein, use of an asymmetric diffuser in an optical stack reduces undesirable defects in a display while maintaining optical gain and/or contrast of the display. The asymmetric diffuser is less diffusive along a first direction that is parallel with linearly extending structures of an associated light directing film
