A retinal projection device to be mounted on a near eye wearable device, the retinal projection device comprising:

• a light source configured to emit laser light;
• a movable mirror configured to perform scanning with the laser light;
• and
• a reflector configured to project an image onto a retina of a user wearing the near eye wearable device by reflecting the laser light having passed through the movable mirror and irradiating the retina with reflected light,
• wherein the reflector includes a plurality of unit regions provided along a surface of a lens of the near eye wearable device, and the surface faces an eyeball of the user, and
• wherein each of the plurality of unit regions is a nanostructure configured to reflect the laser light at a reflection angle corresponding to a position where the unit region is provided when the laser light having passed through the movable mirror is incident on the unit region.
