Provided is an organic EL panel inspection method having a simple configuration and capable of easily screening an organic EL panel that tends to be easily brought into a sudden stop of emission (sudden death), and also provided is an organic EL panel inspection device for performing an inspection using the organic EL panel inspection method. In the organic EL panel inspection method, to determine whether an organic EL panel is good or bad, a plurality of voltages having different values are sequentially applied to the organic EL panel, thereby measuring the respective currents. According to the currents, the following three criteria are checked. In the criterion (1), whether or not a spike current is present in the measured currents is checked. In the criterion (2), between when the plurality of voltages are sequentially applied from one direction to the other direction of the voltage and when the plurality of voltages are sequentially applied from the other direction to the one direction, it is checked whether or not currents having different current densities occur at the same voltage. In the criterion (3), the absolute value of the current density of current flowing when a predetermined voltage in the reverse direction is applied to the organic EL panel is checked. The good/bad determination is made on the basis of one or more of the criteria (1 to 3). |
