Abstract
An organic light emitting display device (OLED) including: a substrate including a plurality of pixel units; first electrodes disposed in the pixel units; first subsidiary electrodes completely covering the top surfaces of corresponding ones of the first electrodes; first electrode protection units disposed on edges of the first electrodes on which the first subsidiary electrodes are not disposed; a pixel defining layer disposed on the substrate, having holes to expose the first electrodes; a light emission layer; and a second electrode disposed on the light emission layer. The light emission layer includes organic emission layers (EMLs) disposed on the first electrodes. The light emission layer may include subsidiary hole injection layers disposed on selected ones of the first electrodes, to vary a distance between the first electrodes and portions of the second electrode.
