  • Publication number: 20130258465
    Abstract: A three-dimensional image display apparatus is described. The three-dimensional image display apparatus includes a display panel and a film-type patterned retarder. The three-dimensional image display apparatus allows the phase retarding regions of the film-type patterned retarder to be deviated from the pixel regions of the display panel so that the line of vision the viewer along the extension of the phase retarding direction corresponds to the pixel regions of the display panel. In other words, the phase retarding regions of the film-type patterned retarder deviate from the pixel of the display panel to avoid the image crosstalk when the viewer looks on the three-dimensional image display apparatus.
