ABSTRACT:
A layer of liquid crystal is present between two supporting plates with a large number of picture electrodes arranged in rows and columns on at least one of the supporting plates. Strip-shaped row electrodes and strip-shaped column electrodes are provided between the respective rows and columns of the picture electrodes. The picture electrodes arranged in rows can be contacted with a respective row electrode by way of at least one micromechanical leaf spring which provides the liquid crystal with a sufficiently steep threshold with respect to the applied voltage, and provides the liquid crystal with a memory when the picture electrodes form picture elements of a display device. Because of this arrangement, the number of lines to be driven of the display device can be extended.
