An optical device comprises a waveguide plate comprising an entrance pupil grating unit, a left pupil-expanding grating unit, and a right pupil-expanding grating unit. The left and right pupil-expanding grating units are bilaterally symmetric, and left and right exit pupil grating units are bilaterally symmetric. An input light is diffracted by the entrance pupil grating unit to form a first left guided light and a first right guided light, the first left guided light is diffracted by the left pupil-expanding grating unit to form a second left guided light, and the first right guided light is diffracted by the right pupil-expanding grating unit to form a second right guided light. The second left guided light is diffracted by the left pupil-expanding grating unit to form a left output light, and the second right guided light is diffracted by the right pupil-expanding grating unit to form a right output light.
