  • Patent number: 9256076
    Abstract: Many pixels (11) are laid out in horizontal and vertical directions on liquid crystal panel (10). There is black matrix (12) between them not to display images. Lenticular lenses (20) are set so that lenticular lenses are inclined at a predetermined angle to vertical direction of liquid crystal panel. Observer observes linear observation region (21) indicated by dotted line through lenticular lenses from predetermined viewpoint. Pixels of liquid crystal panel are parallelograms. Straight line connecting lower right vertex of target pixel to lower left vertex of immediately right pixel is angularly coincide with the observation region. In this way, straight line connecting lower right vertex of target pixel to lower left vertex of immediately right pixel angularly coincides with the lenticular lenses. Consequently, brightness on a screen visible through lenticular lenses becomes constant irrespective of position of observer, which results in reduced moire.
