Abstract: Disclosed is a transparent display device in which a light shield rate is not lowered by partition walls in a light shield mode, and moreover, a light transmittance is not lowered in a transmissive mode. The transparent display device includes a transparent display panel including a plurality of transmissive areas transmitting incident light and a plurality of emissive areas emitting light, and a light control device disposed on a rear surface of the transparent display panel. The light control device is configured to be driven in a transmissive mode where the incident light is transmitted and a light shield mode where the incident light is blocked.
