Claim 8:
9. The head mounted display device of claim 5, wherein the first plate comprises a first structure layer and a second structure layer, wherein
the first structure layer has a plurality of first inclined surfaces and a plurality of first link surfaces, wherein each of the first link surfaces connects different ends of the adjacent first inclined surfaces to form a first zigzag-shaped structure;
the second structure layer has a plurality of second inclined surfaces and a plurality of second link surfaces, wherein each of the second link surfaces connects different ends of the adjacent second inclined surfaces to form a second zigzag-shaped structure, and the second inclined surfaces correspond to the first inclined surfaces and the second link surfaces correspond to the first link surfaces, so that the first zigzag-shaped structure meshes with the second zigzag-shaped structure and the second inclined surfaces and the first inclined surfaces are in contact to form the optical surfaces of the first optical micro structures.
