Method for producing organic light-emitting element, method for aging organic light-emitting element, organic light-emitting element, organic light-emitting device, organic display panel, and organic display device

摘要

A manufacturing method for an organic light-emitting element includes: a first step of forming a first electrode, and forming an organic layer including a light-emitting layer; a second step of forming a second electrode, and thereby forming an element structure including the first electrode, the organic layer, and the second electrode; and a third step of performing an aging process by applying electric power between the first electrode and the second electrode in the element structure. a duration of the application of electric power in the third step is determined as the time elapsed before a time point at which a rate of decrease in a luminance of the light-emitting layer is substantially equal to a rate of decrease in a luminance of the element structure.

1. A manufacturing method for an organic light-emitting element, the manufacturing method comprising:
forming a first electrode, and forming, in correspondence with the first electrode, an organic layer including a light-emitting layer; forming a second electrode in correspondence with the organic layer, and thereby forming an element structure including the first electrode, the organic layer, and the second electrode; and performing an aging process by applying electric power between the first electrode and the second electrode in the element structure, wherein in the aging process, electric power is applied for a duration determined based on a rate of decrease in a luminance of photoluminescence light emission of the light-emitting layer and a rate of decrease in a luminance of electroluminescence light emission of the element structure, the photoluminescence light emission being a luminance of excitation light emitted from the light-emitting layer.
