Organic electroluminescence element, emission chromaticity method of stabilizing organic electroluminescence element, lighting device and an electronic display device

摘要

An organic electroluminescent device having an anode, a cathode, at least on a supporting substrate, an organic compound layer including a light-emitting layer at least one layer of the cathode between the anode, the present invention, at least one layer of the organic compound layer But, organic electroluminescent device containing a luminescent material emission spectrum is shifted to the shorter wavelength side when energized, and a display device using the element, a lighting device.
