Abstract
The present invention provides an organic EL panel and a manufacturing method of the organic EL layer which can slow the reduction in the light emission lifetime of an organic layer and allow a short-circuit defect to be repaired. Organic EL elements include: an organic EL element including a short-circuit portion, and an altered portion formed to be highly resistive by irradiating a cathode with a laser beam; and an organic EL element which does not include the short-circuit portion. In the organic EL element, an organic EL layer emits light when a voltage higher than or equal to a first voltage is applied. In the organic EL element, the organic EL layer emits light when a voltage higher than equal to a second voltage that is higher than the first voltage is applied.
