Abstract

Disclosed is a light diffusing lens having a pointing angle distribution focused toward a lateral direction. The disclosed light diffusing lens includes a light entrance part having a concave shape formed inward from a lower part of the optical diffusing lens, a reflection part having a shape which is concave inward from an upper portion of the light diffusing lens and a light exit portion defined by an outer surface of the light diffusing lens, wherein the light entrance part has a first convex surface which is convex in an optical axial direction defined by a straight line passing through the center of the light diffusing lens as the straight line goes toward the inside of the light diffusing lens.
