A linear illumination device includes a thin and long rectangular parallelepiped optical waveguide member for linearly diffusing light and has a basic construction, which uses a red color light emitting LED as a red color light source provided on a light incident surface of the optical waveguide member and an organic EL element capable of emitting blue color light as a blue color light source. An LED or an organic EL element is used as a green color light source. The organic EL element or elements are arranged such that they reflect back the light emitted from the LED and introduced into the optical waveguide member. An area of a rear electrode of the organic EL element is determined such that the rear electrode covers an upper surface and side surfaces of the optical waveguide member.
