In one embodiment of an invention concerning liquid crystal display devices, a first pixel electrode of a thin film transistor (TFT) array substrate may overlap a slit of a second pixel electrode of the TFT array substrate but not overlap another slit of the second pixel electrode. This may help induce a multi-domain electric field without having to precisely position a common electrode of a color filter substrate and the TFT array substrate. This may prevent position errors, enhance display quality, produce a wider viewing angle, and lower color shift sometimes associated with conventional liquid crystal display devices and methods.
