    摘要: A planar light source, Fresnel lens sheet, and louver are disposed in the stated order in a light source apparatus. The Fresnel lens sheet deflects and focuses in one dimension light that has entered from the planar light source. The louver is disposed in the optical path of the light emitted from the Fresnel lens sheet, and the directivity of the light can be increased by restricting the traveling direction of the light to the focal direction of the Fresnel lens sheet. The light utilization ratio can thereby be increased, the directivity of planarly emitted light can be increased, and the brightness can be made uniform at the point of observation.

    摘要: A light source capable of solving a problem in which the etendue is increased when random polarization is converted into a specific polarization is provided. A relief structure that functions as surface plasmon excitation means for exciting a surface plasmon by a specific polarization component in a polarization direction perpendicular to a first direction in an interface between metal layer 15 and first cover layer 14 in light from emission layer 13 incident on the interface is formed at the interface. The relief structure is periodic in a second direction. Projections 21A of the relief structure are extended along the first direction. A light generation means for generating light having the same polarization component as the particular polarization component from the surface plasmon generated at the interface between metal layer 15 and first cover layer 14 according to the surface plasmon excited by the particular polarization component through the surface plasmon excitation means is formed at the interface between metal layer 15 and second cover layer 16.
