1. Rectroreflective sheet comprises the substrate with bottom surface and body structure surface relative with described bottom surface, and described body structure surface comprises many cube corner elements zone, and described zone comprises:

  • The first area of containing array of cube-corner elements, the optical axis of described cube corner element tilts, thereby has determined on the big incident angle retrodirective reflection performance improved first main plane;

    The second area that contains array of cube-corner elements, the optical axis of described cube corner element tilts, thereby has determined that described second plane is vertical with described first plane on the big incident angle retrodirective reflection performance improved second main plane;

    Wherein said Rectroreflective sheet all has similar substantially retrodirective reflection performance for the light that is incident in the described reflector plate with the incident angle of certain limit in described first plane and second plane.
