Abstract:
A display device with a plurality of gate signal lines extended in the first direction; a plurality of drain signal lines extended in the second direction; a plurality of pixel regions 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. The counter electrode is formed with respect to the pixel electrode by way of an insulation film and is formed every pixel. The pixels include first pixels and second pixels, wherein only the first pixels have a counter voltage signal line which extends in the first direction, and the counter voltage signal line is connected with the counter electrodes in the first pixels. Further, the counter electrodes of the first pixels and the counter electrodes of the second pixels are electrically connected with each other using conductive stride over the gate signal line.
