Abstract: Disclosed is a transparent display device. The transparent display device includes a first display panel, including a transmissive area and an emissive area where a first pixel including a plurality of subpixels displaying an image is provided, and a second display panel including a second pixel provided to overlap the emissive area and the transmissive area of the first display panel, the second display panel being provided on a first surface of the first display panel. The second pixel of the second display panel controls an amount of light incident on the first display panel, thereby preventing a visibility of an image displayed by the first display panel from being reduced by external light.
