Display device and method of manufacturing the same
A display device includes a first island that includes a first display element disposed on a substrate, a second island that includes a second display element disposed on the substrate and spaced apart from the first island, a plurality of connection parts that connect the first island to the second island, through parts formed between the plurality of connection parts and that penetrate into the substrate, and an encapsulation layer that seals the first and second islands, and that includes a first inorganic encapsulation layer and a second inorganic encapsulation layer. The encapsulation layer of the first island includes an organic encapsulation layer, and the encapsulation layer of the second island does not include an organic encapsulation layer.
1 . A method of manufacturing a display device, the method comprising:
forming a plurality of islands, wherein the plurality of islands include display elements disposed on a substrate and are spaced apart from each other;
sealing each of the plurality of islands with an encapsulation layer that includes a first inorganic encapsulation layer and a second inorganic encapsulation layer;
detecting dust material contained on a first island and recording coordinate information about the dust material before or after forming the first inorganic encapsulation layer; and
forming an organic encapsulation layer on the first island that covers the dust material using the recorded coordinate information about the dust material,
wherein the organic encapsulation layer completely covers a top and sides of a protuberance caused by the dust material,
wherein the dust material is disposed directly on a display element of the display elements, the first inorganic encapsulation layer is disposed directly on the dust material, and the organic encapsulation layer is disposed directly on the first inorganic encapsulation layer, wherein the organic encapsulation layer does not extend under the protuberance caused by the dust material,
wherein the protuberance extends above an upper surface of the display element.
