Abstract: A three dimensional (3D) display apparatus can include lenticular lenses between a display panel and a viewing angle control film. The display panel can have a curvature. The viewing angle control film can include a plurality of light-blocking patterns between a first control substrate and a second control substrate. A pitch and a height of the plurality of light-blocking patterns can be determined by a curvature radius of the lenticular lenses, a distance between the viewing angle control film and a set viewing region, and a length of the display panel corresponding to the set viewing region. Thus, in the 3D display apparatus, the quality of 3D images provided to a user can be improved.

Abstract: A 3D display apparatus in which lenticular lenses are disposed on a display panel is provided. The display panel can include pixel regions arranged in a pen-tile shape. For example, the display panel can include a first column of pixel regions in which a first pixel region displaying a first color and a second pixel region displaying a second color are alternatively disposed in a first direction, and a second column of pixel regions in which a third pixel region displaying a third color is disposed, and the first column and the second column can be alternatively disposed in a second direction perpendicular to the first direction. Each of the lenticular lenses can extend in an inclined direction. Thus, in the 3D display apparatus, the rate of color reproduction can be improved in a pen-tile shape.
