3D display apparatus and method for manufacturing the same

A 3D display apparatus, comprising:

• a liquid crystal display panel and a first polarizing filter and a second polarizing filter respectively attached to both sides of the liquid crystal display panel, wherein the 3D display apparatus further comprises:
• a grating functional structure on the second polarizing filter, wherein a stripe direction of the grating functional structure is controlled to form a different predetermined angle with a horizontal direction, wherein the grating functional structure comprises a first grating unit on the second polarizing filter and a second grating unit on the first grating unit, wherein a stripe direction of the first grating unit is parallel to the horizontal direction, and a stripe direction of the second grating unit is parallel to a vertical direction;
• a polarizing filter functional structure on the grating functional structure, wherein functional states of the polarizing filter functional structure is controlled to be switchable between effective and ineffective, wherein when the functional state of the polarizing filter functional structure is effective, the polarizing filter functional structure absorbs one of two linear polarizing light components orthogonal to each other of an incident light;
• when the functional state of the polarizing filter functional structure is ineffective, all of the incident light is transmitted through the polarizing filter functional structure, and
• wherein, in a glasses type 3D displaying mode, only the first grating unit is controlled to function;
• in a naked-eye type 3D displaying mode, only the second grating unit is controlled to function.
