To provide a transparent organic EL display panel that does not impair transparency while light is not emitted, the transparent organic electroluminescence display panel is provided with first transparent electrodes formed on a transparent substrate, a transmittance-adjusting layer formed on the transparent substrate and away from the first transparent electrodes, a partition wall formed on the transparent substrate and the transmittance-adjusting layer so as to partition the first transparent electrodes, a light-emitting medium layer formed on the first transparent electrodes and including at least an organic light-emitting layer, and a second transparent electrode formed on the light-emitting medium layer.
