The invention proposes a large-view-angle holographic display system based on a high focal power liquid lens. The system comprises a collimating beam, an SLM (Spatial Light Modulator), the high focalpower liquid lens, a diaphragm and a CCD, wherein the SLM and the high focal power liquid lens are two core components of the system. When collimating light illuminates the SLM, diffracted light passes through the high focal power liquid lens and the diaphragm, and a reconstructed image can be captured by the CCD. The high focal power liquid lens is composed of an upper substrate, a lower substrate, one multi-layer substrate and two chambers. By using the high focal power liquid lens, a viewing angle of the reconstructed image is expanded.
