The optical film includes a concave lens layer and a birefringence layer. The concave lens layer has plurality of concaves and a presumed refractive index. The birefringence layer overlaps the concave lens layer and includes a plurality of liquid crystal units filled and cured in the concaves. The birefringence layer has a short axis refractive index. The presumed refractive index is between 100.1%-102.8% of the short axis refractive index. The autostereoscopic 3D display includes the optical film, a liquid crystal switch module, and a display panel module. The liquid crystal switch module is disposed on one side of the optical film. The display panel module is disposed on one side of the liquid crystal switch module opposite to the optical film and has a display surface facing the liquid crystal switch module. Image light generated by the display panel module can pass through the optical film after its polarization direction is modulated by the liquid crystal switch module."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical film and autostereoscopic 3D display using the same","description":"An optical film and an autostereoscopic 3D display using the same are provided.
