Abstract
An XY matrix type liquid crystal display panel having a plurality of X electrodes aligned at a given interval in one direction, a plurality of Y electrodes alinged at a given interval in a direction normal to the one direction and a layer of liquid crystal composition disposed between the X and Y electrodes. While an electrode layer forming the Y electrodes is shaped connect divided picture element electrodes, the counterpart forming the X electrodes is arranged to confront with two or more picture element electrodes along the Y axis. Further, each of the Y electrodes is divided into two along the Y axis. A contact area of each of the divided by two Y electrodes extends toward two opposing ends of a support where the Y electrodes are disposed. In a preferred form, the matrix type liquid crystal panel comprises two or more layers of liquid crystal composition and the X and Y electrodes are so arranged that electric field-responsive operating regions of the respective liquid crystal composition layers never are overlapped with one another.
