Patent ID: 10909915

Abstract:
Disclosed is a light emitting device which includes organic electroluminescent sections each including a first electrode layer, an organic light emitting layer, a second electrode layer and a reflective layer in this order, and a light extraction surface. The reflective layer includes two reflective interfaces. In each of the organic electroluminescent sections, a microcavity structure is formed by a structure including a first reflective interface, a second reflective interface, and the two reflective interfaces. The organic electroluminescent sections include first organic electroluminescent sections and second organic electroluminescent sections. The microcavity structure is configured in such a manner that the first reflective interface and the second reflective interface intensify the light in the first wavelength band and the light in the second wavelength band, and that the two reflective interfaces weaken the light in the first wavelength band and intensify the light in the second wavelength band.
