An　electrically　tunable　liquid　crystal　grating　with　two-layer　driving　staggered　electrodes　was　presented,　which　could　replace　the　traditional　slit　liquid　crystal　grating　to　achieve　a　parallax　barrier.　This　grating　avoids　the　blank　area　between　the　single-layer　electrodes　and　expands　the　control　area.　Besides,　it　has　the　advantage　of　fast　switching　time　to　supply　the　loss　of　informations　caused　by　space　division.　A　full　resolution　autostereoscopic　display　was　realized　by　combining　space　division　and　time　division.　Indium-Tin　Oxide　(ITO)　-SiO2-Al-doped　ZnO(AZO)driving　electrodes　with　two-layer　staggered　structure　were　prepared　on　the　glass　substrate　using　lithography　and　vacuum　coating　technology.　Liquid　crystal　was　sandwitched　between　the　substrate　with　driving　electrodes　and　a　substrate　with　common　electrodes　to　form　a　cell　with　a　thickness　of　5　μm.　The　optical　images　show　that　ITO　electrodes　and　AZO　electrodes　with　the　width　of　275.8　μm　are　parallelly　interdigitated　and　isolated　by　SiO2　insulation　layer　on　the　glass　substrate.　A　controllabel　full　resolution　liquid　crystal　was　achieved　by　switching　shading　areas　and　transparent　areas　in　the　role　of　driving　voltage.　©　2015,　Chinese　Optical　Society.　All　right　reserved.
