Abstract: A transparent display panel is provided. The transparent display panel includes a first electrode, a second electrode, and a light-emitting layer disposed between the first electrode and the second electrode. The first electrode is disposed on a light-emitting surface of the light-emitting layer, the second electrode is disposed on one side of the light-emitting layer away from the light-emitting surface, and the second electrode is an electrochromic electrode. The transparent display panel of the present disclosure can reduce an influence of ambient background light on light-emitting pixels without affecting transparent display effect.
