The invention relates to a method for manufacturing a diffusive reflector (450) for a reflective or transflective Liquid Crystal Display (400). The reflector comprises a surface (452) that is structured by means of a photo-embossing process. Herein, a layer (100) of a mixture is provided including a photo-diffusible monomer (102), which may be transported through the layer under the influence of selectively applied irradiation. A layer relief is thus formed, which is preferably developed further at an elevated temperature. The layer is fixed and stabilized by means of a cross-linking step, preferably including thermally induced and/or photo-induced polymerization. In a final step, the polymer relieved surface thus formed is provided with a reflective material (154).
A method of manufacturing a reflector for a reflective or transflective liquid crystal display device, comprising the steps of
A reflective or transflective LCD device, comprising a cell between a front substrate and a rear substrate, said cell including an active layer of a liquid crystalline material, and a reflector for reflecting ambient light modulated by said active layer towards a viewer, wherein said reflector has a polymer surface being provided with a surface relief by means of a photo-embossing process, and at least part of said polymer surface is provided with a reflective material.
