Abstract:
1. Liquid crystal flat screen operating in reflective mode comprising a liquid crystal layer with thickness e 1 confined between first transparent confinement means and second transparent confinement means, the first transparent confinement means being provided with an outer face that will receive incident light arriving on the screen, and an inner face supporting first transparent electrodes used to apply an electric field to the liquid crystal, the second transparent confinement means being provided with an outer face supporting a reflector that will reflect light passing through the second transparent confinement means, and an inner face supporting second transparent electrodes for application of an electric field to the liquid crystal, characterized by one of the following alternatives: either, the second transparent confinement means comprise a layer between their inner and outer faces, forming a colored filter with thickness e or, the first transparent confinement means comprise a layer between their inner and outer faces forming a colored filter composed of a mosaic of elements with width l, and the second transparent confinement means comprise a glass or SiO
