Abstract
A first light guide plate of a light-emitting element is formed by a plurality of strip-shaped light guide bodies arranged in parallel with each other, where each strip-shaped light guide body has a light incident surface on which light from a light source is incident, and a light-emitting surface from which light from the light incident surface is emitted, and on which a plurality of prisms are formed. A second light guide plate of the light-emitting element is positioned so as to face the light-emitting surface side of the first light guide plate, has prisms formed on a surface of the first light guide plate side in a shape that meshes with a shape of the prisms of the first light guide plate, and is formed by a fewer number of light guide bodies arranged in parallel than the strip-shaped light guide bodies.
