Abstract: Provided are an organic light-emitting panel and an organic light-emitting display device including the same. In the organic light-emitting panel, a planarization layer has at least one contact holes in an active area, and first inclination of a first side surface of the planarization layer, located in the non-active area and closest to a dam, with respect to the top surface of the substrate is smaller than a second inclination of a second side surface of the planarization layer, surrounding the contact hole, with respect to the top surface of the substrate. Due to the gentle inclination of the first side surface of the planarization layer, each of the connector electrode, the bank, and the first encapsulation layer disposed on the first side surface of the planarization layer may also have a gentle inclination, such that the second encapsulation layer material having high flowability may flow along the top surface of the first encapsulation layer to cover the surfaces of the planarization layer and the bank in the non-active area. Accordingly, the encapsulation ability of the encapsulation member in a non-active area is improved.

Abstract: Provided are a thin-film deposition mask assembly and a method of fabricating an organic light-emitting display panel using the same. A first mask includes a plurality of first openings disposed in odd columns and a plurality of second openings disposed in even columns. A single second opening disposed in an nth even column, among the plurality of second openings, is disposed between two first openings arranged in a first direction corresponding to row direction transverse to column direction and disposed in at least one column of (n−1)th and (n+1)th columns, among the plurality of first openings, where n is a natural number equal to or greater than 2. In some embodiments, the row direction and the column direction may be perpendicular to each other. The first mask is prevented from sagging.
