Abstract
An optical member includes one or more lens surfaces, each lens surface comprising a curved surface having: a curvature in a first direction, and a curvature in a second direction that is perpendicular to the first direction in an imaginary plane perpendicular to an optical axis of incident light. Each of the one or more lens surfaces has a substantially rectangular planar shape when viewed in an optical axis direction, the substantially rectangular planar shape being defined by two sides substantially parallel to the first direction and two sides substantially parallel to the second direction. The curvature in the second direction continuously increases from a first end of each of the one or more lens surfaces in the first direction toward a second end of each of the one or more lens surfaces in the first direction.
