ABSTRACT:
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.
