摘要： A brighter and whiter reflector provides high reflection efficiency over a wide range of angles. An indenting tool is pressed against the surface of a matrix base material; the pressing operation is repeated while changing the position of the indenting tool on the surface of the base material for the matrix to successively form many pits, the inner surfaces of which are shaped like partial spheres, on the mold surface of the matrix base material so as to provide it as the matrix for forming the reflector. Then, a transfer mold having a mold surface which has a reversed pattern of the pits and projections of the mold surface of the matrix is made, and the mold surface of the transfer mold is transferred to the surface of the base material for the reflector to provide a reflector (1). Pits (4) of the reflector (1) are formed so that the depths the pits (4) range from 0.1 &mgr;m to 3 &mgr;m, the tilt angles of the inner surfaces of the pits (4) are distributed in the range of −18 degrees to +18 degrees, and the pitches between adjoining pits (4) range from 5 &mgr;m to 50 &mgr;m. A reflection type liquid crystal display device in accordance with the present invention is equipped with the reflector (1).
