Patent ID: 7453539

Claim:
A liquid crystal display device comprising: first and second substrates with a liquid crystal layer therebetween; a plurality of gate signal lines which are formed on the first substrate and are extended in a first direction; a plurality of drain signal lines which are formed on the first substrate and are extended in a second direction; and a plurality of pixel regions which are formed on the first substrate in a state that each pixel region includes a switching device, only one pixel electrode which is connected with the switching device and a counter electrode, wherein the counter electrode is laminated by the pixel electrode through an insulation film in the pixel region, the pixel regions include first pixel regions and second pixel regions, the first pixel regions share a counter voltage signal line which extends in the first direction therethrough, and the counter voltage signal line is connected with the counter electrodes in the first pixel regions, the counter electrodes of the first pixel regions and the counter electrodes of the second pixel regions are electrically connected with each other through conductive layers which are formed as striding in the second direction over the gate signal lines, and only the first pixel regions have said counter voltage signal line extending therethrough, and the second pixel regions have no counter voltage signal line extending therethrough.
