1. A liquid crystal display (LCD) panel, comprising:

  • a plurality of unit pixels, wherein each of the plurality of unit pixels comprises an electrode, wherein the electrode comprises;

    a first electrode strip; and

    a second electrode strip;

    wherein the first and the second electrode strips extend from a first end of the electrode at respective first and second angles with respect to a vertical axis of the LCD panel, the first and second angles having opposite angular directions with respect to a horizontal axis of the LCD panel;

    wherein the first and the second electrode strips diverge from the first end over a first portion of the vertical length of the electrode to an intermediate point between the first end and a second end of the electrode, the second end being opposite the first end;

    wherein, from the intermediate point, the first and second electrode strips converge over a second portion of the vertical length of the electrode at respective third and fourth angles with respect to the vertical axis of the LCD panel, the third and fourth angles having the same angular directions as the first and second angles, respectively;

    wherein the first and second electrode strips converge at the second end of the electrode.
