Zusammenfassung:	A display screens includes at least two liquid-crystal cells, the first cell having a first active area and a first transparent sealing region and the second cell having a second active area and a second transparent sealing region. The screen comprises: in a first plane, the first cell and a first transparent sheet of same thickness, the first sealing region being located between the two; in a second plane parallel to the first plane, the second cell and a second transparent sheet of same thickness, the second sealing region being located between the two; the second cell being placed under the first sheet, the second sheet being placed under the first cell so that the first active area is in the exact extension of the second active area.
