Abstract:
A liquid crystal display device includes a first substrate and a second substrate with a liquid crystal material sandwiched therebetween, neighboring first, second, third and fourth regions arranged in a rectangular shape and in a clockwise direction, the first, second, third and fourth regions having a first pixel electrode, a second pixel electrode, a third pixel electrode and a fourth pixel electrode, respectively. The first pixel electrode and the third pixel electrode extend in a parallel direction to one another, and the second pixel electrode and the fourth pixel electrode extend in a parallel direction to one another.
