Document Type and Number:
Japanese Patent JP2818255
Kind Code:
B2
Abstract:
PURPOSE:To obtain an organic EL element having little initial deterioration while stabilizing operation by adding an aging process, which impresses voltage consisting of forward voltage or reverse voltage, or of combined waveform of both voltage to organic electroluminescence element, to a manufacturing process of the organic electroluminescence element. CONSTITUTION:In an organic EL element to be composed of a metal electrode 1 (cathode)/a luminous layer 2/a positive hole implantation layer 3/an ITO electrode 4 (anode), voltage is impressed between anode and cathode to perform aging. As to voltage impression, both of forward voltage and inverse voltage are desirably impressed, further, voltage impression of forward voltage and inverse voltage are to constitutes one time aging and the number of this aging is desirably more than one time. An aging process removes a region generating a leakage current, and positive holes and electrons stored inside the element are removed so that the organic EL element having stable operation and little initial deterioration can be manufactured.
