DEVICE MANUFACTURED BY METHOD FOR APPLYING ACTIVE MATERIAL TO ACTIVE SURFACE

摘要

PROBLEM TO BE SOLVED: To provide an electronic device having an active material deposited by applying an active material for an organic electronic device to an active surface.SOLUTION: An electronic device is an organic electronic device including at least one first active layer and at least one second active layer including at least one active material. In the organic electronic device, (a) the active material in the second active layer is deposited on the first active layer from a liquid composition having a contact angle with the first layer of about 40° or less; or (b) the first active layer having an active surface is treated such that a surface tension thereof after treatment is greater than that before treatment, and the liquid composition is deposited on the active surface of the first active layer, the liquid composition containing at least one active material and a liquid medium having a surface tension that is greater than the first surface tension of the selected active surface; or (c) both (a) and (b) are practiced on the same first active layer or different first active layers.
