Abstract
An organic light-emitting display device comprises a substrate comprising a plurality of sub-pixels, each of the sub-pixels having an emission area and a non-emission area provided to surround the emission area; an auxiliary line disposed in the non-emission area; a first insulating film having a first hole configured to expose a portion of the auxiliary line; an auxiliary line connection pattern disposed on the first insulating film having a protruding portion protruding towards a center of the first hole and overlapping the auxiliary line; at least one bump disposed on the auxiliary line within the first hole and adjacent to the protruding portion of the auxiliary line connection pattern; and a bank having a second hole larger than the first hole to expose the protruding portion of the auxiliary line connection, thereby lowering resistance of a cathode covering a plurality of sub-pixels and preventing lateral current leakage between the sub-pixels through a change of the connection structure between the auxiliary line and the cathode.
