ABSTRACT:
A reflector having light diffusibility for suppressing a reflected image within a wide viewing angle range and having a particular brightness at a specific viewing angle range, and a reflective liquid crystal display device using the reflector, are provided. The reflector1comprises a plurality of light-reflective concave portions3, which are formed on a surface S of a substrate, wherein each of the concave portions3is formed with a first curved surface A1located at one peripheral portion S1of the concave portion3and a second curved surface B1located at the other peripheral portion S2thereof, the deepest point D1is located on the first curved surface A1, and the maximum value σb1of the absolute value of the second curved surface B1to the surface S of the substrate is larger than that of the maximum value σa1of the absolute value of the first curved surface A1to the surface S of the substrate.
