Abstract
A reflection member includes at least one polygonal cell having a polygonally-shaped center bottom part in which a light source is disposed, vertex-part inclined surfaces provided so as to correspond to the respective vertexes of the polygonal shape, and side-part inclined surfaces provided between the corresponding vertex-part inclined surfaces, such that an inclination angle α of at least a part of the vertex-part inclined surfaces to the center bottom part is larger than an inclination angle β of the side-part inclined surfaces to the center bottom part.
