Abstract
The present disclosure relates to a digital hologram display device displaying 3D image as a hologram by using a complex modulation. The digital hologram display device comprising a spatial light modulator including a first pixel outputting a first modulation light by modulating a phase of a first plane-polarized light and a second pixel outputting a second modulation light by modulating the phase of the first plane-polarized light, wherein the second pixel is adjacent to the first pixel; and a light combiner changing a path of the first modulation light outputted from the first pixel so that the path of the first modulation light corresponds to a path of the second modulation light outputted from the second pixel for combining the first modulation light with the second modulation light, wherein a phase of the first modulation light is different from a phase of the second modulation light.
