Abstract
Official abstract text for this publication.
Provided is an illuminating device including a cylindrical lens in which a light incidence surface and a light emission surface, which are opposite to each other, extend in a longitudinal direction, and a light source that is disposed in such a manner that a positional relationship between a paraxial virtual image of the light source due to the light incidence surface of the cylindrical lens and a center of curvature of the light emission surface is in a predetermined range.
