ABSTRACT:
A liquid crystal display apparatus for conducting display in at least two types of display mode using a plurality of pixels arranged in columns and rows, includes: an active matrix substrate having a plurality of pixel electrodes arranged in a matrix formed thereon; a counter substrate opposed to the active matrix substrate, the counter substrate having a first electrode means and a second electrode means; and a liquid crystal layer which is interposed the active matrix substrate and the counter substrate and includes a plurality of liquid crystal regions. The liquid crystal regions have viewing directions different from each other, the viewing directions being determined in accordance with orientations of liquid crystal molecules in the center of the respective liquid crystal regions. At least one of the first electrode means and the second electrode means, which is selected depending on the types of display mode, is used for selectively applying a voltage to the liquid crystal layer together with the pixel electrodes.
