Claim:
1. A liquid crystal display device comprising a liquid crystal exhibiting negative dielectric anisotropy sandwiched between a pair of substrates, wherein liquid crystal molecules constituting the liquid crystal are initially aligned almost vertically to the pair of substrates, and display units each including at least a first pixel for displaying a first-viewpoint image and a second pixel for displaying a second-viewpoint image are arranged in matrix, wherein: the first pixel and the second pixel are constituted with a plurality of sub-pixels, respectively; the liquid crystal display device further comprises an optical element for distributing light from the first pixel and light from the second pixel to different directions; the sub-pixel is constituted with a first domain and a second domain; tilt directions of the liquid crystal molecules when a voltage is applied are within a plane that is at an angle of 45 degrees to a border between the first pixel and the second pixel, are different from each other by 90 degrees between the first pixel and the second pixel, and are different from each other by 180 degrees between the first domain and the second domain; the sub-pixels constituting the first pixel and the sub-pixels constituting the second pixel are arranged in a direction vertical to the border, respectively; the first domain and the second domain constituting the sub-pixel are arranged in a direction in parallel to the border; and the tilt directions of the liquid crystal molecules when a voltage is applied are different from each other by 90 degrees between the display units neighboring to each other in the direction in parallel to the border.
