    摘要： A liquid crystal display apparatus having a plurality of pixels, including: a pair of substrates; a liquid crystal having a negative dielectric anisotropy inserted between the pair of substrates; and first and second electrodes formed on the pair of substrates, respectively. A first alignment control structure is formed linearly on one of the pair of substrates for controlling an alignment of the liquid crystal and a second alignment control structure is formed linearly on the other of the pair of substrates for controlling an alignment of the liquid crystal. The first and second alignment control structures are bent in zigzag fashion and extend parallel with each other. The liquid crystal display apparatus also includes an additional structure for controlling an alignment of the liquid crystal. The additional structure extends from a bent portion of at least one of the first and second alignment control structures.

    摘要： A MVA type liquid crystal panel is slow in a response speed when a black state at a drive voltage about 1V is switched to a low brightness halftone state at the drive voltage about 2 to 3V. According to the present invention, in a liquid crystal display device for driving the MVA type liquid crystal panel, when a liquid crystal pixel at a pixel electrode is changed from a first transmittance to a second transmittance greater than the first transmittance, a drive voltage greater than a fist target drive voltage in correspondence with a second transmittance is applied to the pixel electrode in a first frame period of changing to the second transmittance, and the first target display voltage is applied from a second frame period. According to the present invention, even when either switching is performed from a black state to a low brightness halftone state, from the black state to a high brightness halftone state, for from the black state to a white state, a response time is shortened, and the switching can be performed without generating an overshoot.
