Abstract
A liquid crystal display apparatus includes a first glass substrate with signal electrodes arranged in a striped pattern, a second glass substrate with scanning electrodes arranged in a striped pattern, and a ferroelectric liquid crystal between the first and second glass substrates, the first and second glass substrates facing each other and being fastened so that the signal and scanning electrodes cross each other at right angles. Light blocking members functioning as a black matrix are formed on the first glass substrate so that each light blocking member is placed between adjacent signal electrodes, forms a substantially flat surface with the signal electrodes and is partly buried in the first glass substrate. Metal lines are also buried in the first glass substrate so as to be in contact with the signal electrodes. A similar light blocking member is buried between adjacent scanning electrodes and similar metal lines are arranged on the second glass substrate. It is possible to provide for a liquid crystal display apparatus using ferroelectric liquid crystals a substrate structure which does not cause a difference in level on the substrate due to the black matrix. Moreover, the resistance of the signal and scanning electrodes is lowered by the metal lines.

A liquid crystal display device includes a transparent substrate provided with a plurality of stripe scanning electrodes, and another substrate provided with a plurality of stripe signal electrodes orthogonal to the scanning electrodes, and a liquid crystal layer enclosed between the two transparent substrates. The scanning electrodes are provided on the transparent substrate via a color filter, under overcoat film, and a hard coat film made of hard silicon resin. In the hard coat film, in order to reduce electrode resistance of the scanning electrodes, there are provided a plurality of metal electrodes which are electrically connected individually to the scanning electrodes. The metal electrodes are also connected to the signal electrodes in the same manner as the scanning electrodes.

A switching electrode connected to a switching element is provided on a first substrate. An opposing electrode, an insulation film, and a plurality of sub electrodes are provided on a second substrate. Moreover, a resistant film is provided on a first substrate. A switching electrode which is connected to the switching element and an electrode which is not connected to the switching element are provided on the resistant film. An opposing electrode which is not connected to the switching element is provided on the second substrate. Furthermore, a first electrode which is connected to a first switching element and a third electrode which is not connected to the switching element are provided on the first substrate. The first and third electrodes are opposed to the second electrode, which is connected to a second switching element, via an insulator. The opposing electrode which is not connected to the switching element is provided on the second substrate. Thus, a liquid crystal display device can achieve fast response and even display without a blurred moving image.

To manufacture at a good yield a large-screen display having low resistivity of wires and excelling in flatness of substrates, a metal material, a transparent electrode material, and a conductive resin are used for forming either scanning electrodes or signal electrodes, or both of the same. Not less than two materials are used as the metal material, while amorphus ITO is used as the transparent electrode material. An electrode substrate has electrode structures in each of which a metal wire made of the foregoing metal material, a transparent electrode made of the foregoing transparent electrode material, and a conductive resin layer are laminated in this order on a transparent substrate. Conductivity is imparted to the conductive resin layers by conductive particles electrodeposited by the micell electrolytic method.
