A viewpoint controllable liquid crystal grating was presented, which was driven by two-layer staggered electrodes to control the deflection of liquid crystal molecules. AZO-SiO2-AZO driving electrodes with two-layer staggered structure were prepared on the glass substrate using lithography and vacuum coating technology. This grating avoids the blank area between the single-layer electrodes and expands the control area. Therefore the control area becomes complete and flexible. The optical images shows AZO electrodes and AZO electrodes with the width of 275.8are parallel interdigitated and isolated by SiO2 insulation layer on the glass substrate. Combining the drive circuit, the liquid crystal grating could control the ratio of the light shielding area and transmission area effectively. It has some application prospects in the field of three-dimensional display
