The optical member includes an integrator including a first fly-eye lens on which light from the solid-state light-emitting device is incident and a second fly-eye lens on which light from the first fly-eye lens is incident, and uniformizing a luminance distribution of light in a predetermined illumination region illuminated with light incident from the solid-state light-emitting device. A major-axis direction of a luminance distribution shape of light incident on an incident plane of the first fly-eye lens is different from arrangement directions of the cells in the first fly-eye lens."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Illumination unit, projection display unit, and direct-view display unit","description":"An illumination optical system including one or more light sources each including a solid-state light-emitting device and an optical member.
