ABSTRACT:
A liquid crystal display apparatus includes a vertical alignment type liquid crystal cell including a first substrate formed with a first electrode, a second substrate formed with a second electrode, and a liquid crystal layer containing liquid crystal molecules given a pretilt angle. A pair of polarizer plates sandwiches the cell, and a driver device applies a voltage of a multiplex driving waveform across the first and second electrodes. In a display in-plane parallel to a surface of the first or second substrate, at least one of the first and second electrodes has a zigzag border alternately coupling a first border perpendicular to display in-plane components of directors of liquid crystal molecules in a middle area along a thickness direction of the liquid crystal layer in the absence of applied voltage and a second border extending along a direction crossing the first border.
