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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical stack with asymmetric diffuser","description":"The present disclosure describes an optical stack that includes an asymmetric diffuser.
