Abstract: An optical waveguide display substrate includes a first base substrate (10); a reflective element (1) on the first base substrate (10), the reflective element (1) comprising a first surface facing the first base substrate (10), a second surface on an opposite side of the reflective element (1) from the bottom surface, and two light-receiving surfaces connecting the first surface to the second surface at opposite ends of the reflective element (1); and a first film assembly between the first base substrate (10) and the reflective element (1), the first film assembly comprising a first optical layer (2) and a second optical layer (3) on the first optical layer (2). A refractive index of the first optical layer (2) may be smaller than a refractive index of the second optical layer (3). A display device includes the optical waveguide display substrate.
