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　275.8　are　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　©　2016,　Science　Press.　All　right　reserved.
