Abstract: This disclosure provides a light source assembly and a display device, and the light source assembly includes: a first substrate and a second substrate arranged opposite to each other; a waveguide layer arranged between the first substrate and the second substrate; and a side-incident collimated light source arranged on a side of the waveguide layer, wherein the refractive index of the waveguide layer is higher than the refractive index of the first substrate, and the refractive index of the second substrate respectively; and light of the side-incident collimated light source is incident onto the side of the waveguide layer at a preset angle, and the incident light is totally reflected at the interference between the first substrate and the waveguide layer. In the embodiments of this disclosure, the light of the side-incident collimated light source is reflected totally at the interface between the waveguide layer and the first substrate under the principle of total reflection, and refracted at the interface between the waveguide layer and the second substrate, that is, the light is radiated from the surface of the second substrate, thus improving the efficiency of the light exiting from the single side of the light source assembly.
