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.

Abstract: A method of manufacturing a display device according to an embodiment of the present disclosure can include placing a mask on an adhesive layer of a display panel and irradiating light thereon, and transferring a plurality of light emitting diodes on a donor onto the display panel. The adhesive layer can be configured by a plurality of first parts overlapping the mask and a second part which is exposed from the mask to be irradiated with light. Further, a light emitting diode alone which is in contact with the plurality of first parts can be transferred onto the display panel.
