Title:
MANUFACTURING METHOD OF ORGANIC EL ELEMENT
Document Type and Number:
Japanese Patent JP2006092886
Kind Code:
A
Abstract:

To provide an aging processing process capable of surely opening and breaking a defective part of an organic EL element, and capable of preventing the organic EL element from being broken even when the thicknesses of organic layers are the same and emission areas thereof are different from one another.

This manufacturing method of an organic EL element 7 includes at least: an element formation process S1 for forming, on a translucent glass substrate 2, the organic EL element 7 with organic layers 5 sandwiched between transparent electrodes 3 and a back electrode 6; and an aging processing process S3 for applying a recovery voltage Vr comprising a predetermined reverse bias voltage between both electrodes comprising the transparent electrode 3 and the back electrode 6 after the element formation process S1 to break a defective part 12 of the organic EL element 7. The recovery voltage Vr in the aging processing process S3 is set between the maximum reverse voltage R in actually driving the organic EL element 7 and a breakdown voltage V of the organic EL element 7 depending on a capacitance component of the organic layers 5.
