Abstract

Disclosed is a white organic light emitting device (200, 300, 400, 500, 600) in which a life of a device is enhanced. In some embodiments, the white organic light emitting device (200, 300) includes a first emission part (110) between a first electrode (102) and a second electrode (104) and a second emission part (120) on the first emission part (110). At least one among the first and second emission parts (110, 120) includes an emission area control layer (190, 290). In some embodiments, the white organic light emitting device (400, 500, 600) includes a first emission part (110) between a first electrode (102) and a second electrode (104), a second emission part (120) on the first emission part (110), and a third emission part (130) on the second emission part (120). At least one among the first to third emission parts (110, 120, 130) includes an emission area control layer (390, 490, 590).
