ABSTRACT:
A liquid crystal display arrangement is provided with two liquid crystal cells containing twisted-nematic material, and positoned one cell behind the other. Both cells are between a pair of crossed polarizers, and the arrangement can be used to selectively reverse the contrast of a display or it can be used as a matrix display in which cross-talk between adjacent elements is minimized.
