3D display apparatus having lenticular lenses
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.
