Abstract
The present invention relates to method for depositing an organic material for an organic light emitting device and an organic light emitting device manufactured thereby. The method includes the steps of: applying a premix in which a host and a dopant are premixed, to a first donor substrate; heating the premix by applying an electric field to the first donor substrate; depositing the host and the dopant separated into different layers on a second donor substrate, with the host or the dopant having a relatively low vaporization temperature first deposited from the premix onto the second donor substrate and then the dopant or the host having a relatively high vaporization temperature deposited later onto the second donor substrate; heating the host and the dopant by applying an electric field to the second donor substrate; and depositing the host and the dopant that are uniformly mixed on a target substrate.
