Abstract: The present disclosure provides an organic light-emitting display device having a plurality of pixels arranged along first and second directions that intersect each other. Each of the pixels includes: a transistor; at least one insulating layer on the transistor, and a pixel contact hole extends through the insulating layer and exposes part of the transistor; a first electrode on the at least one insulating layer and connected to the transistor via the pixel contact hole; and a filling layer on the first electrode and filling the pixel contact hole. A first bank has a plurality of first openings, and each of the first openings exposes at least one of the first electrodes. A second bank has a plurality of second openings, and each of the second openings exposes a plurality of the first electrodes arranged along the second direction.

Abstract: An organic light emitting diode display device includes a substrate having pixel areas which are defined in a matrix form in first and second directions intersecting each other; a plurality of first electrodes each arranged in the corresponding pixel areas; a first bank having at least one first opening through which at least part of the first electrode is exposed; a second bank covering a part of the first bank and having at least one second opening through which at least part of the first electrode is exposed; and an organic emission layer disposed in the first opening. The second opening extends in the first direction so that the plurality of first electrodes arranged in the first direction is exposed through the second opening.
