Title:
ORGANIC ELECTROLUMINESCENCE ELEMENT, AND LIGHT EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/104175
Kind Code:
A1
Abstract:
This color-adjustable organic electroluminescence element can suppress power consumption, and comprises a first light emitting unit and a second light emitting unit that emits light of a shorter wavelength than that of the light emitted by the first light emitting unit, wherein angle θ1, at which the light emission intensity of the first light-emitting unit is maximal, and angle θ2, at which the light emission intensity of the second light-emitting unit is maximal, satisfy [θ1 ≤ θ2 (wherein 0°≤θ1≤θ2 < 90°)], θ1 and θ2 being measured from the front direction.
