Abstract
The invention provides an electro-optical device that includes: an electro-optical panel; light sources that emit light that enters the electro-optical panel; an optical waveguide board that guides the light emitted from the light sources toward the electro-optical panel; and a flexible printed circuit board on which the light sources are mounted, wherein the flexible printed circuit board is adhered to the optical waveguide board by adhesive members in such a manner that a part of the flexible printed circuit board is opposed to a surface of the optical waveguide board and that the light sources are positioned to be opposed to an edge face of the optical waveguide board, and concave portions are formed in the optical waveguide board at least at positions where the adhesive members are provided.
