Abstract: A transparent display device includes a substrate on which a pixel including an emission area and a first transparent area is defined, and a light-emitting diode provided in the emission area and including a first electrode, a light-emitting layer, and a second electrode. The transparent display device further includes an anti-deposition layer provided in the first transparent area. The height of the light-emitting layer at an edge area of the emission area is higher than the height of the light-emitting layer at a center area of the emission area. Further, the second electrode is disposed over the entire surface excluding the first transparent area, and the height of the anti-deposition layer at an edge area of the first transparent area is higher than the height of the anti-deposition layer at a center area of the first transparent area.
