    摘要： A display device includes a substrate including a display area and a non-display area surrounding the display area, a plurality of pixels on the substrate in the display area, a first encapsulation layer on the substrate to cover the pixels and including an inorganic material, a second encapsulation layer on the first encapsulation layer and including an organic material, and a third encapsulation layer on the second encapsulation layer and including an inorganic material. An edge of the second encapsulation layer is located in the non-display area, edges of the first encapsulation layer and the third encapsulation layer are located more to an outside than the edge of the second encapsulation layer is. The first encapsulation layer includes a first area and a second area located more to the outside than the first area and having a surface roughness smaller than a surface roughness of the first area.

    摘要： A display device includes: a substrate including a first display area, a second display area including a light-transmitting part, and a third display area between the first and second display areas; a first subpixel including a first TFT on the first display area and a first light-emitting element on and electrically connected to the first TFT; a second subpixel including a second TFT on the third display area and a second light-emitting element, which is on the second display area and does not overlap with the second TFT in a plan view; a thin-film encapsulation layer on the first and second subpixels,; and a first transparent conductive layer between the second TFT and the second light-emitting element to electrically connect the second TFT and the second light-emitting element. The thin-film encapsulation layer has a refractive index of about 1.5 to about 1.7.
