An OLED device (100) according to an example embodiment includes an organic light-emitting element (120) between a lower substrate (110) and an upper substrate (150). At least a part of a side surface of the upper substrate (150) has a reverse-tapered shape configured to reduce damage to the lower substrate (110) caused by deformation of the upper substrate (150) due to an external impact. Accordingly, reliability issues resulting from a short circuit or burnt lines due to the deformation of the upper substrate (150) may be resolved, improving overall reliability and productivity of an OLED device. |
