This paper introduces the principle, design solution and verification method of auto-stereoscopic display using an electric-field-driven LC lens. In order to realize the optimal 3D performance, professional software simulation and trail verification were used to adjust the design solution. It provides that a novel design about the electrode, specially discuss the distribution law of cell gap and refractive index, and the effect of retardation on 3D crosstalk. Using novel electrode structure and the rule of LC cell retardation to design electric-field-driven LC lens, 3D crosstalk can be reduced to below 3%, the 3D module show excellent 3D image quality. It has very important significance to design and study the electric-field-driven LC lens.
