Provided is a holographic display device. The holographic display device includes a light source unit configured to emit a light, and a spatial light modulator (SLM) configured to modulate at least one of a phase and amplitude of the light emitted from the light source unit to output a hologram image, and including a plurality of pixel groups that are arranged in a first direction, wherein each of the plurality of pixel groups includes: first pixels arranged in a matrix x1×y1 and providing an image having a first wavelength, and second pixels adjacent to the first pixels in the first direction, arranged in a matrix x2×y2, and providing an image having a second wavelength that is different from the first wavelength.
