1. A near-eye display device, comprising:
a first optical cavity, comprising, in sequential order: a first prism, a first reflective polarizing film prism, a phase delay film, a wedge-shaped lens, and a second prism;
a second optical cavity, comprising a plurality of array lenses arranged in sequence; and
a first reflector, being disposed in correspondence with one end of the plurality of array lenses and the first reflective polarizing film prism;
wherein the first optical cavity, the second optical cavity and the first reflector are configured to enable an image source to:
be reflected into the first optical cavity through the first prism, pass through the first reflective polarizing film prism, the phase delay film and the wedge-shaped lens in sequential order, then pass through the wedge-shaped lens and the phase delay film after being reflected by the second prism, be reflected into the plurality of array lenses through the first reflective polarizing film prism, enter the first reflector through one end of the plurality of array lenses, be reflected back to the plurality of array lenses through the first reflector, and be reflected into an human eye through the plurality of array lenses.
