ABSTRACT:
A flat panel display having an improved picture quality is disclosed. In one embodiment, a first pixel electrode and a second pixel electrode are formed in each subpixel area. The electrodes enclose an open space (gap) such that their outer boundary has a substantially rectangular shape. The flat panel display may also include a capacitance electrode coupled to the second pixel electrode to form a coupling capacitor. In use, the coupling capacitor operates such that a magnitude of a voltage applied to the first pixel electrode is lower than an applied data voltage, and a magnitude of a voltage applied to the second pixel electrode is higher than an applied voltage. The different voltages operate such that a tilt direction of LC molecules disposed above the first pixel electrode differs from a tilt direction of LC molecules disposed above the second pixel electrode.
