A reflector and a liquid crystal display device in which original reflection characteristics can be sufficiently accomplished and moire patterns can be prevented are provided. A reflector 30 formed with a plurality of concave portions 28b.sub.1, 28b.sub.2 on one surface of a base member along one arrangement direction is employed. When defining the section passing through the deepest point of the concave portion as a first section and defining the section perpendicular to the first section at the deepest point as a second section, the concave portions 28b.sub.1, 28b.sub.2 have symmetrical shapes on the basis of the first section and have asymmetrical shapes on the basis of the second section. When defining the directions along the first section in the concave portions 28b.sub.1, 28b.sub.2 as axis directions L.sub.1, L.sub.2, each of the axis directions L.sub.1, L.sub.2 are not parallel with the arrangement direction, and the axis directions L.sub.1, L.sub.2 are set to two or more directions.
