A quantum dot optical function panel and its preparation method comprises a functional layer, a condensation layer and a diffusion layer which compose a multilayer structure. Said functional layer is located between condensation layer and diffusion layer. The functional layer comprises a main layer and quantum dots uniformly distributed in main layer. Said condensation layer comprises a condensation substrate layer and condensation bulges distributed over the upper surface of condensation substrate layer. Said diffusion layer comprises a diffusion substrate layer and diffusion bulges distributed over the lower surface of diffusion substrate layer. The condensation layer and diffusion layer of the quantum dot optical function panel of the present invention can resist oxygen and water vapor to a certain extent, protecting the quantum dots well.
