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.

A trimmed resistor is provided which has no directional feature when used and is easily mounted on a printed base board. In the trimmed resistor, there are formed four external electrodes arranged at peripheral portions of a rectangular insulation base plate in a point symmetrical distribution about a center of the insulation base plate, a film-like resistance body connected with all of the external electrodes, and a protective film covering the film-like resistance body. Two electrodes among the above-mentioned four electrodes are used as resistor terminals, and a cut slit for trimming is formed in the resistance body longitudinally or as starting from a side of the electrodes serving as resistor terminals.

A new driving technique is disclosed for a liquid crystal display panel for displaying at least two rows of characters and a cursor line while scanning scanning lines of the panel, which technique can decrease the number of scanning lines and increases the above defined voltage margin by scanning the scanning lines each two rows at a time in a line sequential scanning fashion and skipping the scanning of a cursor line electrode in a row where a display of the cursor line is unrequired, thus ensuring good contrast and viewing angle characteristics of the panels.
摘要:
A liquid crystal display device containing a fluorescent material comprises a pair of electrodes, a pair of substrates, and an element for making liquid crystal mixtures in such a molecular orientation that the fluorescent materials generate no fluorescence at a selected portion of the pair of electrodes and accordingly no fluorescence penetrates through the liquid crystal mixtures. The element comprises a liquid crystal molecule orientation layer made of a layer of surfactant or electric power sources. The liquid crystal molecule orientation is formed over the pair of electrodes to produce a homeotropic orientation of a nematic mesophase. The electric power sources are applied to the pair of electrodes to form the homeotropic orientation of the nematic mesophase in a background area of the display device opposed to a display area of it.
