Abstract

PURPOSE:In a slub type light guiding path comprising a film layer of a dielectric material which is sandwiched between separate dielectric materials having a refractive index lower than that of the layer, it is intended to reduce the angle of divergence at which light is emitted to the outside by gradually thinning the thickness of the film layer to a wedgelike shape.
