Abstract

An organic light emitting display device includes a substrate having a display area including a plurality of sub pixels and a non-display area which encloses the display area, a thin film transistor on the substrate, a planarization layer on the thin film transistor, an anode which is disposed on the planarization layer and is disposed for each sub pixel, a bank layer which is disposed on the planarization layer and includes a first opening unit exposing at least a part of the anode and a second opening unit spaced apart from the first opening unit, a first spacer on the bank layer, and a second spacer which is continuously disposed on the anode and the bank layer so as to overlap with a part of an edge of the first opening unit, and the bank layer has a reverse tapered shape and the second spacer has a tapered shape.
