Patent ID: 8310639

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 the first direction; a plurality of drain signal lines which are formed on the first substrate and are extended in the second direction, each one of the drain signal lines has a wide portion and a narrow portion; and a plurality of pixel regions which are formed on the first substrate in a state that each pixel region includes a switching device, a pixel electrode which is connected with the drain signal line and a counter electrode, wherein the counter electrode is formed on the substrate side with respect to the pixel electrode by way of an insulation film and is formed every pixel, at least one of the pixel regions comprises first pixels and second pixels, wherein only the first pixels have a counter voltage signal line which extends in the first direction, and is arranged only in the first pixels and the counter voltage signal line is connected with the counter electrodes in the inside of the first pixels, the first pixels only are associated with one of the narrow portions of the drain signal line and the second pixels only are associated with one of the wide portions of the drain signal line; the counter electrodes of the first pixels and the counter electrodes of the second pixels are electrically connected with each other using conductive layers which are formed in a state that the conductive layers stride over the gate signal lines, and wherein a substantial portion of the drain signal line of the second pixels is the wide portion, a substantial portion of the drain signal of the first pixels is the narrow portion, the width of the wide portion is wider than the width of the narrow portion, and the wide portion of the drain signal line of the second pixels is formed at the position that does not overlap the gate signal line.
