To reduce the speckle noise generated in holographic 3D displays, we proposed the phase disturbing device using randomly-fluctuated liquid crystal (LC) alignment. Optical simulations showed that the phase disturbance can reduce the speckle noise. In addition, the parameters corresponding to the alignment fluctuation of thick LC were quantitatively evaluated.
