Abstract: A holographic display device and a method for generating a hologram are disclosed. The holographic display device generating a hologram may include a storage unit and a control unit. Herein, the storage unit may store at least one look-up table each having a partial size of a full size of sub-holograms for reconfiguring object points, wherein the object points are included in a scene reconfigured of the generated hologram. And, the control unit may use at least one look-up table each having the partial size, so as to calculate hologram values of the sub-holograms for reconfiguring object points, wherein the object points are included in the scene, and then the control unit may generate the hologram by overlapping the hologram values of the sub-holograms.
