Abstract: An optical waveguide, which includes a medium layer and N semi-transmissive, semi-reflective films supported by the medium layer. The semi-transmissive, semi-reflective films are arranged in sequence along a first direction perpendicular to a thickness direction of the medium layer. The orthographic projections of two adjacent semi-transmissive, semi-reflective films on a plane parallel to the thickness direction of the medium layer have an overlap region. A contour of each semi-transmissive, semi-reflective film is a curved surface structure, curved surface structures of the N semi-transmissive, semi-reflective films are N continuous sub-curved surfaces formed by segmenting a same curved surface respectively, a sum of heights of the N sub-curved surfaces is a height of the curved surface, and a concave side of the curved surface structure of each semi-transmissive, semi-reflective film faces towards a same bottom surface of the medium layer.
