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.

Abstract: A transparent display device includes a substrate on which a pixel including first, second, and third emission areas and first and second transparent areas arranged along a first direction is defined, a light-emitting diode disposed in each of the first, second, and third emission areas and including a first electrode, a light-emitting layer, and a second electrode, and an auxiliary electrode extending in a second direction perpendicular to the first direction and electrically connected to the second electrode. The first emission area and the auxiliary electrode are disposed between the first transparent area and the second transparent area, and the second transparent area includes a first portion between the first emission area and the second emission area. Further, the first transparent area has a higher transmittance than the second transparent area.

Abstract: An electroluminescent display device includes a plurality of sub-pixels arranged on a substrate along a first direction and a second direction crossing the first direction, and a light-emitting diode disposed in each of the plurality of sub-pixels and including a first electrode, a light-emitting layer and a second electrode, wherein among the plurality of sub-pixels, the sub-pixel of an nth row and an mth column has a same color as the sub-pixel of an (n+1)th row and an (m−1)th column, where n is a natural number and m is a natural number large than 4, and wherein among the plurality of sub-pixels, the sub-pixel of the nth row and a kth column has a same color as the sub-pixel of the nth row and a (k−2)th column, where k is a natural number smaller than or equal to m.
