Organic light-emitting display device

Abstract:

An organic light-emitting display device including a substrate on which a plurality of sub-pixels are arranged; a thin film transistor and a first electrode of an organic light-emitting diode connected to the thin film transistor, the thin film transistor and the organic light-emitting diode being disposed in each of the plurality of sub-pixels; a first bank layer disposed on the first electrode and exposing the first electrode; and a second bank layer disposed on the first bank layer and exposing the first bank layer and the first electrode. Further, the first bank layer includes first regions overlapping with via holes through which the thin film transistor is connected to the first electrode and second regions which are regions other than the first regions, and a thickness of the first regions is greater than a thickness of the second regions.
