Abstract: A plurality of cells are formed by a polygonal cell having even number of sides being at least six sides, and a plurality of cells being constructed by a polygonal shape as a unit are arranged in a display region regularly, so as to construct the dot matrix type information display panel. Therefore, it is possible to provide a dot matrix type information display panel: in which lines in a longitudinal and lateral directions are not so emphasized when an image information such as characters and so on which are displayed based on a line; in which a dot does not look in such a manner that a quadrangular shape collapses and an interference fringe (moire) is not generated as in the case of the honeycomb-shaped partition walls; and in which an image such as sharp and natural characters and so on which are displayed based on a line can be displayed.

Abstract: The invention relates to a liquid crystal display device (1) with a negative display when no current is supplied. Said device comprises a liquid crystal layer that is built into an active zone (2) between substrates, the exterior of each of said substrates being covered by pole filters that are aligned in an arrangement for the currentless negative display. The interior of said substrates is provided with segments (2.2) of surface electrodes that are separated from one another by means of electrically insulating dividing lines (5), said segments being connected to connection lines that lead to the exterior. Masking is provided on the interior of the substrate for areas that would otherwise remain bright during retrace blanking. The invention provides an advantageous construction and display quality, as the periphery of the active zone (2) is encompassed by adhesive strips (4), which appear black, between the substrates, and the masking, at least in bright areas that would otherwise be visible from a conventional viewing distance during retrace blanking, is produced by means of additional adhesive strips (4').

Abstract: A twist-nematic liquid crystal display includes a first substrate and a second substrate disposed to oppose to the first substrate with distance d1 therebetween, either one of the first and second substrates being a transparent substrate; a plurality of pixel electrodes formed on either one of a surface of the first substrate and a surface of the second substrate, said surfaces opposing to each other; a common electrode formed on other one of the surfaces respectively of the first and second substrates, a voltage applying unit for applying a voltage between the pixel electrodes and the common electrode, twist-nematic liquid crystal sandwiched between the first and second substrates, molecules of the liquid crystal respectively having long axes continuously twisted between the first and second substrates. When the twist-nematic liquid crystal has a birefringence index (retardation) of Δn, Δn x d 1 > 2 µm is satisfied, where d 1 is expressed in micrometers. This provides a liquid crystal display in which transmittivity in a base section in which pixel electrodes are not disposed is almost equal to transmittivity in a non-selected section in which pixel electrodes are disposed.

Abstract: A liquid crystal composition is interposed between first and second substrates, and a plurality of picture elements are constituted of scanning electrodes and signal electrodes arranged in a matrix. Switching transistors are provided in the picture elements, connected to picture element electrodes and can operate while the major-axis direction of the liquid crystal molecules is maintained almost parallel with the surfaces of the substrates by means of the picture element electrodes and a common electrode facing to the picture element electrodes. In addition, the signal electrodes, picture element electrodes, and shield electrodes which are positioned between each signal electrode and to which a potential can be always applied from the outside are formed in the picture elements. This liquid crystal display device does not require any transparent electrode, has an excellent visual property and high contrast, and is free from cross-talk.
