Original Abstract Submitted
A diffractive light waveguide apparatus, a near-eye display device, and a manufacturing method for a diffractive light waveguide apparatus are provided. The diffractive light waveguide apparatus includes a waveguide substrate and a grating structure. The grating structure is arranged on a surface of the waveguide substrate and includes multiple grating units, the multiple grating units have a first period in a first direction and a second period in a second direction, and the second direction is different from the first direction. The first period and the second period are adjustable to cause a two-dimensional pupil expansion angle of the grating structure to be 180°.
