Patent ID: 7403193

Claim:
An image display device is characterized in that a pair of electrodes are formed on each pixel within an image display part of a substrate, one of the pair of electrodes includes a counter electrode to which a counter voltage supply signal which becomes a reference with respect to signals supplied to another electrode of the pair of electrodes is supplied, a drive circuit which supplies signals to the respective pixels through signal lines arranged in a plane of the substrate is formed outside the pixel display part, the drive circuit is constituted of a plurality of semiconductor devices, a counter voltage signal line arranged in the plane of the signal lines of the substrate which supplies counter voltage signals to the counter electrode is formed on a region between one semiconductor device and another semiconductor device which is arranged adjacent to the one semiconductor device, and a dummy line is arranged in both of the plane of the signal lines of the substrate and in the plane of the counter voltage signal line of the substrate and between the signal lines in the plane of the substrate and the counter voltage signal line in the plane of the substrate outside of the image display part; wherein the dummy line is formed in the plane of the substrate along with both the signal lines in the plane of the substrate and the counter voltage signal line in the plane of the substrate so as to extend along at least one of the signal lines.
