10. the method for making of 3D display device according to claim 6 is characterized in that, said first polaroid comprises Triafol T layer and polyvinyl alcohol layer, and said inside surface in said phase delay layer forms said first polaroid, comprising:
Triafol T layer and polyvinyl alcohol layer are provided;
Said Triafol T layer and said polyvinyl alcohol layer fit together form said first polaroid;
Said first polaroid is attached to the inside surface of said phase delay layer, and makes said Triafol T layer adjacent with said phase delay layer;
Perhaps, Triafol T layer and said polyvinyl alcohol layer are stacked in the inside surface of said phase delay layer successively, thereby form said first polaroid at the inside surface of said phase delay layer.
11. the method for making of 3D display device according to claim 6; It is characterized in that; Said first polaroid comprises Triafol T layer, polyvinyl alcohol layer and Triafol T layer, and said inside surface in said phase delay layer forms said first polaroid, comprising:
Triafol T layer and polyvinyl alcohol layer are provided;
Successively said Triafol T layer, said polyvinyl alcohol layer and said Triafol T laminating are lumped together and form said first polaroid;
Said first polaroid is attached to the inside surface of said phase delay layer;
Perhaps, Triafol T layer, said polyvinyl alcohol layer and said Triafol T layer are stacked in the inside surface of said phase delay layer successively, thereby form said first polaroid at the inside surface of said phase delay layer.
