Abstract
An OLED device and a method for fabricating the same are disclosed, capable of improving yield and preventing decomposition of organic layers by moisture. An organic passivation layer having excellent morphology is applied to prevent a short circuit between an anode electrode and a cathode electrode. A Ca layer is applied to remove moisture from the inside of the device, thereby increasing the lifespan of the device. Accordingly, generation of dark sports by the short circuit caused by protrusions on a poor-morphology layer can be prevented. In addition, moisture absorbent layers are formed between the passivation layers and the partitions to remove outside moisture and the moisture outgassed from the inside, that is, partitions and organic layers, thereby elongating the lifespan of the OLED device.
