Abstract:
1. An organic light emitting display comprising: a substrate; a thin film transistor positioned on the substrate; a planarization layer positioned on the thin film transistor; an emission unit positioned on the planarization layer and electrically connected to the thin film transistor; a passivation layer positioned on the substrate to cover the thin film transistor, the emission unit and an edge portion of the planarization layer; and a cover substrate attached to the substrate, wherein the substrate is attached to the cover substrate with a sealant, wherein the sealant is positioned in a space between the substrate and the cover substrate to cover an edge portion of the passivation layer, and wherein the planarization layer, the passivation layer, and the sealant each have a normal taper edge portion, and taper angles of the edge portions of the planarization layer, the passivation layer, and the sealant range from 15° to 60°, respectively.
