Abstract
An apparatus for displaying a hologram comprises: a hologram display panel that represents light having the hologram images to an observer; a detecting camera that decides a position of the observer; a deflector that forms a prism pattern to refract the light corresponding to the detected position of the observer; and a deflector driver that supplies a driving voltage corresponding to a inclined angle for forming the prism pattern, wherein the deflector includes: a plurality of first electrodes running to a first direction and divided into a plurality of electrode groups; a plurality of connection electrodes running to a second direction crossing with the first direction, and connecting same numbered first electrodes of the electrode groups, wherein each end of the connection electrodes forms a pad portion; and a second electrode facing to the plurality of the first electrodes with a liquid crystal cell therebetween.
