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 liquid crystal display TV includes a TV housing, and a reflective type liquid crystal display panel installed in the housing. A magnifying lens is disposed for magnifying an image on the display area and a support assembly is provided for supporting the magnifying lens to allow a space where the ambient light enters from above a display area of said liquid crystal display panel when the magnifying lens lens is in use. This arrangement allows full utilization of the ambient light for the optical performance of the liquid crystal display panel.

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.
摘要:
A multi-layered liquid crystal display device is disclosed, which includes a stack of liquid crystal layers in which the longitudinal axes of the liquid crystal molecules extend spirally, the liquid crystal layers being disposed in parallel with the spiral axes. A voltage supply is provided for supplying a voltage to at least a portion of the liquid crystal layers for conversion of the molecular alignment. Also provided is a pair of polarizers for making visible the conversion of the molecular alignment. More particularly, the polarization direction of the polarizers or direction normal to the polarization direction is deflected within the range of 3.degree. to 15.degree. with respect to the longitudinal direction of the liquid crystal molecules in a sense to reduce the spiral angle of the liquid crystal layers and the deflection angle is substantially in alignment with the longitudinal direction of the liquid crystal molecules.
