Reflectors for reflective LCDs must be designed to be able to control the direction of the image and the viewing angle range for optimal display. In this paper, we tried to optimize the reflector for reflective LCDs. The conventional surface structures showed many defects and problems. Therefore we made efforts to improve the surface structures of the conventional reflectors through both a theoretical approach and analytic work. As a result, we proposed surface structures which showed almost uniform reflectance within the viewing angle range specified by a user even at any oblique incidence. By using Beckmann's equations, we could check the reflective property of the proposed surface structures.
