PURPOSE: A light diffusion member is provided to prevent the surface of a base layer in separation, assembly, conveying process by reducing a contact area of a lamp guide pin through a protrusion. CONSTITUTION: In a light diffusion member, a light diffusion member(100) is installed on the light source(50). The light diffusion member comprises a structural layer formed at the one side of the base layer. A structural layer of the light diffusion member comprises a plurality of stereo-structures. The stereo-structure comprises a first section having curvature around a peak and a second section having the base layer and inclination angle at both side of the first section. The second section is composed of a line with a creation inclination angle form the base layer. The second section has inclination angle of 30°~50° or 130°~150° from the base layer.
