In this paper, a holographic 3D display system with wide viewing angle and large size is proposed based on a tunable liquid crystal grating. The proposed system shows a viewing angle of 57.4°, which is nearly 7 times of the conventional case with a single spatial light modulator, and the size of the reconstructed image is enlarged by about 4.2 times.
