LIGHT-EMITTING DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

A light-emitting element is disclosed that can drive at a low driving voltage and that has a longer lifetime than the conventional light-emitting element, and a method is disclosed for manufacturing the light-emitting element. The disclosed light-emitting element includes a plurality of layers between a pair of electrodes; and at least one layer among the plurality of layers contains one compound selected from the group consisting of oxide semiconductor and a metal oxide, and a compound having high hole transportation properties. Such the light-emitting element can suppress the crystallization of a layer containing one compound selected from the group consisting of oxide semiconductor and a metal oxide, and a compound having high hole transportation properties. As a result, a lifetime of the light-emitting element can be extended.
