A naked-eye 3D display film structure includes a polarization component and a light column lens assembly overlaid on the polarization component. The light column lens assembly has multiple arc-column-shaped lenses sequentially connected with each other. A hetero-component is disposed between each two adjacent arc-column-shaped lenses. The arc-column-shaped lenses and the hetero-components are sequentially connected with each other and periodically arranged. The hetero-components serve to enhance the intensity of the emergent light outgoing from the gaps periodically arranged between the arc-column-shaped lenses and destruct the forming condition of the Moiré pattern so as to reduce the periodical contrast of the emergent light of the respective arc-column-shaped lenses. Accordingly, the naked-eye observation 3D image quality and effect are enhanced.
