A liquid crystal display device includes an array substrate and a counter
substrate, a liquid crystal cell held between the substrates 300 and
containing liquid crystal molecules arranged to have an alignment
corresponding to alignment properties of inner surfaces of the substrates,
first and second polarizing plates having individual polarization axes and
mounted on outer surfaces of the first and second substrates,
respectively, a pixel electrode and counter electrode formed on the array
substrate to apply a lateral electric field substantially parallel to the
first and second substrate into the liquid crystal cell. The liquid
crystal display device controls the alignment of the liquid crystal
molecules by the lateral electric field between the pixel and counter
electrodes. Particularly, in the liquid crystal display device, an optical
retardation plate is interposed at least between the first polarizing
plate and the array substrate, and an optical axis and retardation value
of the optical retardation plate are determined to compensate for twisting
of the alignment of the liquid crystal molecules caused upon application
of the lateral electric field.
