The optical sheet includes: a sheet-like base layer; a light control layer having unit shaped elements arranged in a direction parallel to a sheet surface of the base layer; and a light diffusing layer disposed between the base layer and the light control layer. The light diffusing layer includes a binder resin portion and particles dispersed in the binder resin portion. The particles in the binder resin portion includes a single particle and an aggregate formed of aggregated single particles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical sheet, surface light source device and transmission type display device","description":"There is provided an optical sheet which can prevent problems when it is superimposed on another member.
