Abstract: An optical waveguide display having an embedded light source is provided. The optical waveguide display having an embedded light source includes a light source unit including a plurality of light sources for generating light according to an applied voltage and an optical waveguide display unit including a plurality of optical waveguides on which the light generated by the light source unit is incident. The light sources are aligned to be adjacent to the optical waveguides of the optical waveguide display unit in one panel so that the light generated by the light sources is directly incident on the optical waveguides. Accordingly, in the optical waveguide display having the embedded light source, optical loss is reduced. Also, the size of the outward shape of the display is reduced since a complicated optical structure can be simplified. The display is able to withstand a large amount of shock from the outside, and gray scale levels can be easily controlled.
