A reflection type liquid crystal display device having a wide viewing angle, and capable of assuring a light utilization factor at or above a certain value for bright display even when conditions of an external light are varied is provided. The reflection type liquid crystal display device comprises (a) a liquid crystal cell comprising an upper substrate, a lower substrate and a liquid crystal layer between the substrates, (b) a polarizing film provided in a side of the upper substrate in the liquid crystal cell, (c) light reflecting means provided in a side of the lower substrate in the liquid crystal cell; and (d) an optical member provided between the polarizing film and the liquid crystal cell, and having a retardation axis when it is viewed in the normal direction. An angle between an absorption axis of the polarizing film and the retardation axis of the optical member is within a range of about 88° to about 92° or about −2° to about +2° . A retardation value in relation to the normal direction of the optical member is within a range of about 50 nm to about 500 nm.
