The first uniaxial optical film layer comprises a plate portion and a plurality of refraction portions. The plate portion is disposed on the reflective grating film layer. The plurality of refraction portions are disposed on a side of the plate portion away from the reflective grating film layer, and are either curved columns or quadrangular prisms. The second uniaxial optical film layer is laminated on a side of the plate portion adjacent to the refraction portions. The plurality of refraction portions are accommodated in the second uniaxial optical film layer. The second uniaxial optical film layer has an ordinary refractive index less than an extraordinary refractive index of the first uniaxial optical film layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical composite film, display panel, and display device","description":"An optical composite film comprises a reflective grating film layer, a first uniaxial optical film layer, and a second uniaxial optical film layer.
