A composite optical reflective film for a backlight source system and a preparation method therefor. The composite optical reflective film comprises a transparent diaphragm (4) and a reflective diaphragm (2), wherein the reflective diaphragm (2) is spliced to the transparent diaphragm (4) through an adhesive (3), and the other face of the reflective diaphragm (2) is coated with a reflective coating (1). The composite optical reflective film has good dimension stability, is not easy to warp and deform, has a higher reflectivity, has a simple preparation process and is easy to operate. |
