ABSTRACT:
A reflective liquid crystal display device comprising a reflector with a number of small convex portions of the same shape is provided. The reflector is formed by patterning a photosensitive resin applied to one surface of a core substrate to a predetermined pattern so as to form a number of small convex portions, heat-treating the surface having the convex portions, and covering the surface with a reflective film. By suitably selecting the shape of the convex portions, the reflective properties of the reflector are controlled.
