ABSTRACT:
The liquid crystal display of the present invention includes: a first insulating substrate as an array substrate; display pixels formed in such a manner as to be arranged in array like shape on the first insulating substrate, said display pixels having pixel electrodes electrically connected to each other; a counter substrate formed on a second insulating substrate on which common electrodes are formed; a liquid crystal layer interposed between the first insulating substrate and the second insulating substrate, the first insulating substrate and the second insulating substrate being bonded each other; a transfer electrode for supplying a common electrical potential to common electrodes on the second insulating substrate through a conductive material; wherein the transfer electrode is formed by patterning a conductive thin film that has been formed by the last conductive film forming process of the first insulating substrate; wherein a second conductive metal film, which has been formed in the second conductive film forming process of the first insulating substrate, and is connected to the common electrode potential, and the conductive thin film are connected to each other on the periphery of the transfer electrode through a contact hole or through a direct contact, and the conductive thin film is directly formed on the first insulating substrate at one portion of the center portion of the opening of the transfer electrode.
