Abstract:
A light emitting apparatus includes a transparent substrate made of glass material, for example, a first electrode layer formed on the substrate, a light emitting functional layer including organic material formed on the first electrode layer, a back surface electrode made of metallic material, for example, as a second electrode layer formed on the light emitting functional layer, and dot-shaped conductors arranged on the first electrode layer. The dot-shaped conductors made of low electric resistivity material are arranged at the first electrode layer. The combined resistance value of the transparent electrode and the plurality of dot-shaped conductors becomes lower than the resistance value of the transparent electrode alone. Therefore, voltage drop occurred at the transparent electrode can be effectively suppressed.
