Stereoscopic display optical film and manufacturing method and product thereof

The invention provides a three-dimensional display optical film and a manufacturing method and a product thereof. The three-dimensional display optical film comprises a base material layer, a light condensation layer, a filling and leveling layer and an image-text layer. The light condensation layer is arranged on one side of the base material layer. The filling and leveling layer is arranged on the side, away from the base material layer, of the light gathering layer. The image-text layer is arranged on the side, away from the light condensation layer, of the base material layer. Wherein the refractive index n1 of the light gathering layer is larger than the refractive index n2 of the filling layer, and the thickness D of the stereoscopic display optical film and the thickness D1 of the base material layer meet the following relation: 0 < (D-D1)/D1lt; 1. In the embodiment of the invention, the filling and leveling layer can fill and level up the surface of the light condensation layer, and abrasion and pollu
