The 3D that this utility model provides shows in film, is respectively provided with the first structure sheaf and the second structure sheaf on the first relative optical surface and the second optical surface of substrate layer.Wherein the first post mirror layer in the first structure sheaf, the axially extending direction of its first post mirror unit and the axially extending direction of the second post mirror unit of the second post mirror layer orthogonal (namely axially extending direction is mutually perpendicular to) in the second structure sheaf.This just can make 3D show, and film has the 3D effect in transverse and longitudinal both direction.Simultaneously, in this first structure sheaf except including the first post mirror layer, the first post mirror layer surface away from the first optical surface is additionally provided with the first packed layer that refractive index is different from, the surface that first packed layer and the first post mirror layer contact is and the convex-concave surface of the first post mirror layer laminating, and the first packed layer is flat surface away from the surface of the first post mirror layer.Such setting can make two-layer post mirror layer have good post mirror effect respectively when transverse and longitudinal is placed, and film is no matter when laterally disposed or placed longitudinally, is respectively provided with good 3D effect to make 3D show.In a word, this 3D is shown that film is fitted on display panels, no matter laterally disposed for screen or vertically place, all can obtain good 3D effect, it is possible to meet consumer demand to a greater extent.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
