Abstract (en)
[origin: WO2006021681A1] The invention concerns a liquid crystal display device comprising two substrates (10, 20) provided with respective electrodes (12, 22) and located on either side of a layer of liquid crystal molecules (30) and means defining two stable states for the liquid crystal molecules, in the absence of an electric field. The invention is characterized in that it further comprises a mask (100) including transparent areas (120) allowing through only the design of the areas to be visualized and opaque areas (110) covering the rest of the surface of the display and among others the zones not addressed by the electrodes (12, 22) and, in that the electrodes (12, 22) are configured such that their edges are located in zones outside the transparent areas (120) of the mask (100), in that each electrode block (28) consists of the assembly of interconnected elementary areas through multiplexing and of intermediate zones located beneath the opaque areas (110) of the mask (100), and that on at least one of the substrates (10, 20), the electrodes are formed of blocks (28) which cover the entire surface of the substrate except the intermediate zones (281) of small width required for providing electrical insulation between the blocks.
