Abstract

Within a matrix display type liquid crystal display having a first family of electrodes aligned in one direction at least the viewing side of which is made of transparent conducting material, a second family of electrodes aligned in a different direction crossed with said one direction, and a liquid crystal material between the both families of the electrodes, a respective one of the electrodes of at least one family of said both electrode families is made up of a picture element electrode and a wiring electrode for connecting the picture element electrodes and an extension electrode connected to the wiring electrode and an electrode width at a portion thereof other than a picture element area wider than the picture element are for the purpose of reducing the resistance of the wiring electrode.

Claims

1. An electrode structure for a matrix-type liquid crystal display including a first group of spaced parallel electrodes disposed in a first plane, a second group of spaced parallel electrodes disposed in a second plane and orthogonally crossing said first group of electrodes, said first and second groups of electrodes being disposed opposite each other and spaced with liquid crystal material interposed therebetween, each electrode of said first group of electrodes comprising:

a wire extending transversely to said second group of electrodes, said wire defining a continuous, electrically-conductive path of a predetermined width in said first plane;

a first electrode portion disposed opposite to the electrodes in said second group connected to and extending from said wire in said first plane; and

extension electrodes connected to and extending from said wire in said first plane in regions between said first electrode portions which are not opposite to an electrode in said second group, said extension electrodes defining an electrically-conductive path which is wider in said first plane than the conductive path defined by said wire.

2. An electrode structure for a matrix-type liquid crystal display including a first group of spaced parallel electrodes disposed in a first plane, a second group of spaced parallel electrodes disposed in a second plane and orthogonally crossing said first group of electrodes, said first and second groups of electrodes being disposed opposite to each other and said planes being spaced with liquid crystal material interposed therebetween, each electrode of said first group of electrodes comprising:

a wire extending transversely to said second group of electrodes, said wire defining a continuous, electrically-conductive path of a predetermined width in said first plane;

a first electrode portion disposed opposite to the electrodes in said second group connected to and extending from said wire in said first plane; and

coating means on said wire in said first plane in regions between said first electrode portions which are not opposite to an electrode in said second group for reducing the resistance of said wire in said regions.
