Abstract: A near-eye display device and a wearable device having the same. The near-eye display device includes a laser generation module, an optical waveguide element, and a holographic optical element; the laser generation module is configured to emit parallel laser beams; the optical waveguide element has an in-coupler area and an out-coupler area, the optical waveguide element is configured to receive the parallel laser beams and output the parallel laser beams in parallel after one-dimensional pupil expansion or two-dimensional pupil expansion; the holographic optical element has interference fringes and is attached to the out-coupler area, the holographic optical element is configured to receive the parallel laser beams from the optical waveguide element and to reflect or transmit the parallel laser beams by diffraction to output a plurality of converging image light beams.
