Abstract
An organic light-emitting display (OLED) device and a method for manufacturing an OLED device are provided. A thin-film transistor is disposed on a lower substrate. An organic light-emitting element is disposed above the thin-film transistor and includes an anode, an organic light-emitting layer on the anode and a cathode on the organic light-emitting layer. A passivation layer is disposed on the organic light-emitting element and includes hydrogen. The hydrogen absorption layer includes at least one hydrogen absorption layer coming in contact with the top surface and/or the bottom surface of the passivation layer. The OLED device can suppress the performance of the thin-film transistor from degrading by using the hydrogen absorption layer that absorbs residual hydrogen in the passivation layer.
