    Abstract: A louver film, a planar light source device, and a liquid crystal display device enables further improvement of directivity for visibility while light use efficiency is maintained and also enable improvement of viewing angle contrast and halo. The louver film includes a plurality of lenses which are arranged at a constant pitch on an emission side of a light source; a first support disposed on a side closer to the light source than the lenses and has a thickness greater than or equal to the pitch of the lenses and a refractive index of 1.5 or greater; and a light reflecting layer disposed on a side closer to the light source than the first support and has a reflectivity of 90% or greater and openings on optical axes of the plurality of lenses, and the opening ratio of each opening is in a range of 30% to 70%.
