Abstract
The present disclosure relates to a holography three dimensional display in which no 3D cross-talk problem is arisen. The present disclosure suggests an apparatus for displaying hologram images comprising: a display panel displaying a hologram image; a back light unit disposed at one side of the display panel for supplying a back light; a first light path deflecting cell disposed at another side of the display panel facing away from the back light unit for forming a first prism pattern along a first direction rotating by a predetermined angle from a horizontal axis of the display panel; and a second light path deflecting cell disposed in front of the first light path deflecting cell for forming a second prism pattern along a second direction perpendicular to the first direction.
