Patent ID: 8841928

Claim:
An organic EL panel inspection method for inspecting whether an organic EL panel provided with an organic EL element is superior or inferior, the method comprising: a step of applying a plurality of voltages having different values successively in sequence to the organic EL panel, and measuring each electric current; and a step of judging whether the organic EL panel is superior or inferior based on the measured electric currents; wherein the step of judging whether the organic EL panel is superior or inferior is carried out based on at least one of a judgment reference 1, a judgment reference 2, and a judgment reference 3; wherein the judgment reference 1 represents a presence or absence of a spike-like electric current in the measured currents, the judgment reference 2 represents a presence or absence of generation of electric current having different current density at an identical voltage between when the plurality of voltages are applied successively from one end in the sequence of the plurality of voltages to the other end and when the plurality of voltages are applied successively from the other end to the one end, and the judgment reference 3 represents an absolute value of current density of an electric current flowed when a predetermined voltage is applied to the organic EL panel in a reverse direction.
