Title:
TANDEM TYPE ORGANIC LIGHT EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/111534
Kind Code:
A1
Abstract:
The present invention relates to a tandem type organic light emitting device and, more specifically, to a tandem type organic light emitting device which exhibits low operation voltage, high power efficiency and an excellent color rendering index (CRI). To this end, the present invention provides a tandem type organic light emitting device, the device comprising: a base substrate; a first electrode formed on the base substrate; a second electrode formed to oppose the first electrode; and first to third organic light emitting layers formed in sequence from the first electrode, between the first electrode and the second electrode. The first organic light emitting layer comprises a first light emitting layer for emitting blue light, the second organic light emitting layer comprises a second light emitting layer for emitting yellow light, and the third organic light emitting layer comprises a third light emitting layer for emitting red light.
