Abstract
The present disclosure belongs to the field of display technology, and particularly relates to an optical waveguide display substrate, a manufacturing method thereof, and a display apparatus. The optical waveguide display substrate comprises a side light source, an alternating-electric-field electrode structure, and a light scattering layer, wherein the side light source is provided at at least one side of the light scattering layer, the light scattering layer is switchable between a transparent state and a light scattering state under influence of an alternating electric field applied by the alternating-electric-field electrode structure, so that incident light from the side light source is scattered out of the optical waveguide display substrate to form a display image, and the light scattering layer comprises a polymer network and a light scattering liquid crystal material.
