ABSTRACT:
A liquid crystal display device includes a liquid crystal layer, a pixel electrode, a switching element, a signal line, and a same potential line. The liquid crystal layer is composed of liquid crystal that has a negative dielectric anisotropy and so is vertically aligned in an initial alignment state. The pixel electrode has a first side and a second side. The first side being opposite from the second side. The switching element is used for applying driving voltage selectively to the pixel electrode. The signal line is connected to the switching element and is located adjacent to the first side of the pixel electrode. The same potential line extends in the same direction as the signal line and is applied with the same voltage as that applied to the signal line. The same potential line is located adjacent to the second side of the pixel electrode.
