Abstract
There is provided a parallax barrier filter realizing far higher brightness than a conventional barrier filter. A large number of aperturesare arranged obliquely and at equal intervals in a parallax barrier filterof a five-parallax type. For a five-parallax type, the aperturesare rectangles with the same shape and the same area, and under the condition that an opening height is 8/7 times as large as a sub-pixel height, that is, the opening height Ht=8/7Hsp, an opening width is set to 2-2.5 times as large as a sub-pixel width. A positional relation between the adjacent aperturesis that based on expressions Pt=5·Wsp and Dtr=(5/7)·Wsp, where Pt is a pitch of the plural aperturesalong a lateral direction X and Dtr is a deviation amount between the aperturesadjacent in a vertical direction Y.
