Abstract
(EN)
An optical composite film, comprising a reflective grating film layer, a first single-optical-axis optical film layer and a second single-optical-axis optical film layer. The first single-optical-axis optical film layer comprises a plate-shaped portion and a plurality of refractive portions, the plurality of refractive portions being selected from one of a curved prism and a quadrangular prism. The extraordinary light refractive index of the first single-optical-axis optical film layer is greater than the ordinary light refractive index of the first single-optical-axis optical film layer; and the extraordinary light refractive index of the second single-optical-axis optical film layer is greater than the ordinary light refractive index of the second single-optical-axis optical film layer, and the ordinary light refractive index of the second single-optical-axis optical film layer is less than the extraordinary light refractive index of the first single-optical-axis optical film layer.
