Means for displaying a hologram

The present disclosure relates to an apparatus for displaying a hologram, the present disclosure proposes an apparatus for displaying hologram images before, comprising: a hologram display panel (10) for reproducing light which has the hologram images to an observer; a detecting camera (90) for deciding a position of the observer; a deflector (30) for forming a prism pattern to redirect the light corresponding to the detected position of the viewer; and a Deflektortreiber (60) for supplying a driving voltage corresponding to an oblique angle to form the prism pattern, wherein the deflector (30) comprises: a plurality of first electrodes (33) running in a first direction and divided into a plurality of electrode groups are; a plurality of connecting electrodes (331) running in a second direction intersecting the first direction, and the like numbered first electrodes of the electrode groups connects with each end of the connection electrodes (331) forms a contact patch area; and a second electrode (34) opposite the plurality of first electrodes with a liquid crystal cell between them.
