1. A liquid crystal display apparatus comprising:

  • a liquid crystal display panel including a TFT substrate having pixels in which first electrodes and power supply means for supplying a power voltage to the first electrodes are respectively formed, and a first alignment layer on which at least one first alignment groove is formed by rubbing in a first rubbing direction, a color filter substrate having second electrodes opposite to the first electrodes, a second alignment layer on which a second alignment groove is formed by rubbing in a second rubbing direction, and red, green and blue color filters, a liquid crystal interposed between the TFT substrate and the color filter substrate, the liquid crystal being tilted by the first and second alignment groove and being twisted when the power voltage is applied to the first and second electrodes, and a light-leakage preventing means for masking a non-effective display region being displaced between the pixels and a light leakage region, the light leakage region being adjacent to the non-effective display region, being displaced over a portion of the first electrodes, a reverse tilted liquid crystal being over the portion of the first electrodes, and the reverse tilted liquid crystal being caused by a rubbing the first alignment groove in the first rubbing direction when the power voltage is applied to the first and second electrodes; and

    a backlight assembly for providing a light to the liquid crystal display panel.
