Abstract
The present invention provides a method for repairing an organic EL element and a method for manufacturing an organic EL panel that can reduce a production cycle time. A method for repairing an organic EL element includes an application step of repeatedly applying a pulse voltage having ON-period and OFF-period to an organic EL element. In the application step, the pulse voltage is a forward voltage or a reverse voltage, and the ON-period is equal to or longer than a time constant that is the product of an element capacity of the organic EL element and a wiring resistance including the element.
