Abstract
A near-eye display device, comprising: a pixel island assembly, comprising a plurality of light-emitting elements; and a microlens array assembly, comprising a microlens array and an optical surface member, the optical surface member having an optically transmissive free-form surface, a planar total-reflection surface and an optically reflective free-form surface, each surface of which intersects with other two surfaces; wherein light emitted by the pixel island assembly enters the optical surface member through the optically transmissive free-form surface, is reflected by the planar total-reflection surface and by the optically reflective free-form surface in sequence, and then exits the optical surface member through the microlens array.
