Title:
ORGANIC ELECTROLUMINESCENCE ELEMENT, AND LIGHT EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/104174
Kind Code:
A1
Abstract:
This color-adjustable organic electroluminescence element has two or more layer-form light emitting units and three or more layer-form electrodes sandwiching the light emitting units, comprises a first light emitting unit and a second light emitting unit that emits light of a longer wavelength than that of the light emitted by the first light emitting unit, and can increase light intensity within a specific range of angles from the front direction, 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.
