Abstract
Provided is an organic light emitting display device in which a plurality of pixel areas each including an emitting area and a non-emitting area is defined in a display area. The organic light emitting display device includes: an auxiliary electrode in a part of a non-emitting area of at least one pixel area; an auxiliary electrode contact portion formed as a part of the auxiliary electrode; a first electrode in the emitting areas of the plurality of pixel areas; an organic layer on the first electrode and the auxiliary electrode; and a second electrode on the organic layer. The auxiliary electrode contact portion electrically connects the auxiliary electrode and the second electrode. A distance from a center of the auxiliary electrode contact portion to a terminal end of the first electrode in the emitting area may be 3 μm or more.
