Abstract
An organic light-emitting display device includes a substrate defining an emission area and a non-emission area; an insulating layer on the substrate and having at least two grooves being defined at a portion of the insulating layer corresponding to the non-emission area; a first electrode on the insulating layer at a portion of the insulating layer corresponding to the emission area; an auxiliary electrode on the insulating layer and spaced apart from the first electrode, the auxiliary electrode being on at least a portion of the insulating layer having the at least two grooves; a bank pattern on portions of the first and auxiliary electrodes; a barrier on the auxiliary electrode and separated from the bank pattern, the barrier being formed of a same material as the bank pattern; an organic light-emitting layer on the first electrode; and a second electrode on the organic light-emitting layer.
