We present a near-eye display featuring triple-channel waveguide with chiral liquid crystal gratings. Our is capable of dividing one field view into three through both the polarization orthogonality and angular separation. To illustrate its principle, k-space diagram, which takes account aspect ratio view, depicted. results demonstrate that diagonal reaches 90°, eye relief 10 mm, exit pupil 4.9 × mm2, transmittance 4.9%, uniformity 89%.
