摘要： The light-emitting unit has at least a first light-emitting element, a second light-emitting element, and a separation layer. The separation layer has a leg portion and a stage portion which protrudes outside of a bottom surface of the leg portion over the leg portion. An upper electrode of the first light-emitting element is electrically connected to a lower electrode of the second light-emitting element in a region where the upper electrode and the lower electrode overlap with the stage portion of the separation layer. By providing the separation layer, the light-emitting unit can be formed without using a metal mask. The upper electrode can be a composite material including an organic compound and a metal oxide or a stacked layer of the composite material and a metal material or a light-transmitting conductive material.

摘要： The present invention is a fabrication method of a light-emitting device characterized by ejecting a solution containing a luminescent material toward an anode or a cathode under a reduced pressure and characterized in that in a duration before the solution is arrived at the anode or the cathode, the solvent in the solution is volatilized, the remaining part of the luminescent material is deposited on the anode or the cathode, and thereby formed a light-emitting layer. By the present invention, a baking process for thickness reduction is not required after applying the solution. Accordingly, it is possible to provide a fabrication method with high throughput although the method is low in cost and simple.

Therefore, the present invention can provide a light-emitting element typified by an organic EL element in which a range of choice of materials that can be used as the intermediate conductive layer is broadened extremely, and which can realize a high light-emitting efficiency, a low power consumption and a high reliability, and further a display device using the light-emitting element.
