Title:
LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/179528
Kind Code:
A1
Abstract:
According to the present invention, a first light-emitting part (140a) and a second light-emitting part (140b) are provided with organic layers (120a, 120b) between electrodes, respectively. The film thickness between the electrodes of the first light-emitting part (140a) is at least 95% and no more than 105% of the film thickness between the electrodes of the second light-emitting part (140b). In addition, the peak wavelength of the emission spectrum of the first light-emitting part (140a) differs from the peak wavelength of the emission spectrum of the second light-emitting part (140b). The number of layers between the electrodes of the first light-emitting part (140a) is the same as the number of layers between the electrodes of the second light-emitting part (140b).
