An optical guide for a near-eye display device includes a first guide element having a light input zone and a second guide element having an output zone. The first guide element is superimposed on the second guide element. The optical guide also includes an optical coupling system between the first guide element and the second guide element, and the first and second guide elements have, on the first part of their length, a mutual spacing so as to delimit a thin layer of air between said guide elements extending between a first longitudinal end of the guide elements and the optical coupling system. The optical coupling system, located at a second longitudinal end of the first and second guide elements, includes a single-piece portion of the guide elements, associated with an optical reflection member to propagate the beams of light from the input zone toward the output zone.
