A display device includes an organic light emitting element and a cover layer. The organic light emitting element includes a thin-film encapsulation layer comprising an aluminum-containing material. The cover layer is disposed on the thin-film encapsulation layer, and the cover layer includes a silicon containing unit, an aluminum containing unit, and a bridging unit, and the aluminum-containing unit of the covering layer is covalently bonded to the thin-film encapsulating layer. A method of manufacturing a display device includes providing a dual-curable sol-gel composition comprising a silicon-containing monomer, an aluminum-containing monomer, a solvent, and a polymerization initiator, applying the composition to a thin-film encapsulation layer of an organic light-emitting device; and curing the composition with a UV radiation and at a curing temperature to form a cover layer on the thin-film encapsulation layer, wherein the curing temperature is a temperature that does not damage the organic light-emitting element. |
