ABSTRACT:
The present invention is a light-controlling sheet for making light emitted from light sources uniform and/or converging the light. The light-controlling sheet includes a lens part having a large number of rod-like unit lenses arranged in parallel, with a lens surface of each unit lens facing to the light-exiting side. A cross section of the lens surface of each rod-like unit lens taken perpendicularly to the longitudinal direction of the unit lens is asymmetrical. The lens surface of each unit lens has a flat surface part in the shape of a flat surface, and a curved surface part in the shape of part of a cylindrical surface.
