Summary:The disclosure provides an optical waveguide, a manufacturing method of an optical waveguide, and a head-mounted display device. The optical waveguide has a first optical region and a second optical region for transmitting an image beam. The optical waveguide includes a plate body, multiple first light-guiding optical elements, and multiple optical microstructures. The first light-guiding optical elements are disposed in parallel lines on a light-guiding plane inside the plate body. The light-guiding plane is located in the first optical region, and there is a spacing between the adjacent first light-guiding optical elements. The image beam transmitted to he light-guiding plane is separated into multiple sub image beams, and the transmission paths of the sub image beams are at least partially different. The optical coupling-out structure is disposed in the plate body and is located in the second optical region.
