Title:
LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/046881
Kind Code:
A1
Abstract:
A second electrode (130) overlaps a first electrode (110), and a third electrode (150) overlaps the second electrode (130). A first organic layer (120) is positioned between the first electrode (110) and the second electrode (130), and a second organic layer (140) is positioned between the second electrode (130) and the third electrode (150). A first current source (220) is connected to the first electrode (110), and a second current source (240) is connected to the second electrode (130). A control unit (210) controls the first current source (220) and the second current source (240). The peak wavelength of the emission spectrum of the first organic layer (120) differs from the peak wavelength of the emission spectrum of the second organic layer (140).
