An organic electro-luminescent display device includes barriers in a non-display area to protect a display area from water and oxygen. Barriers may include a permeation prevention barrier, a voltage contact portion, and a blocking layer. A permeation prevention barrier includes contact portions where a barrier layer having a lower permeability than a passivation layer penetrates through the passivation layer. A voltage contact portion penetrates the passivation layer so that a signal supply line contacts a conductive material. A blocking layer covers a wall, a planarization layer, and an inorganic insulation layer, and has a lower permeability than the planarization layer, the wall, and the inorganic insulation layer. The permeation prevention barrier, the voltage contact portion, and the blocking layer may be used in various combinations.

Organic electro-luminescent display device

The invention provides display devices that minimize permeation of oxygen and moisture, as well as methods of manufacturing such display devices. A display device according to the present invention includes an insulating substrate, a cover substrate connected to the insulating substrate, and a display element positioned between the insulating substrate and the cover substrate. The display device further includes a first sealant along an edge of one of the insulating substrate and the cover substrate, the first sealant including a first part and a second part spaced apart from each other, a second sealant provided along the edge of the other of the insulating substrate and the cover substrate, the second sealant being arranged between the first part of the first sealant and the second part of the first sealant, and an encapsulation film interposed between the first sealants and the second sealant.
