Furthermore, by the solubility by lowering, and, in its turn light emitting, such as a layer of other layers coated on one surface thereof even if polymerized by coating liquid since the do not dissolve in layer, said formed other layers can be. I.e., to facilitate multilayer structure formed in this case, high efficiency, low drive voltage and a long life organic EL element, .can be produced at low cost. A hole-transporting compound the polymerization layer, in terms of flowing TEOS to 95-105 sccm, hole transport with repeating units preferably including polymer or oligomer.

Furthermore, at least one 2 polymerizable preferred that the hole-transporting compound into a desired function is mixed at the ratio of and may be used, polymerizable substituents with hole transport which has no may used as a light-weight. said polymerizable layer, organic EL of, hole injection layer, hole transport layer, electron transport layer, electron injection layer applied, luminous efficiency, in terms of life characteristics, in particular hole injection layer, it is preferred that a hole transport layer.

Hole injection layer and hole transport layer and interlayer dielectric and is composed of gold, in which either of the polymerization, polymerization to form the both is interlayer dielectric and is composed of gold. Furthermore, film thickness of these layers, but is no limited to, extracts of Barks of, preferably is 10 ∼ 100 nm, it is still more preferably in 20 ∼ 60 nm, most preferably is 20 ∼ 40 nm..

The present invention according to the "adjacent 2-storey", hole injection layer hole transport layer, hole transport layer and a light emitting one of the layers is preferably not less.

Furthermore, polymerization disclosure disclosure polymerization connections necessary hitherto an acid by decomposition temperature agent disclosure or polymers, organic EL compound layer-type semiconductor layer, and, in particular metal complexes by reacting is formed or longevity luminous efficiency can be the thought of. Therefore, adjacent 2 during-storey, polymerization just a layer close to the anode disclosure agent, this layer of polymers which can be dispense from the active agent to connections necessary hitherto disclosure by polymerizing other layer by, while also being capable of multi-layer board, the light emitting layer are less influence agent disclosure polymerization, having superior or luminous efficiency organic EL device can be produced.

In the present invention, polymerization processes employing the cross-linkable substituents having hole transport compounds including mixture, therefrom or a layer to control the properties as needed to, leveling or vesicles (leveling agent) number ([...]), crosslinked number, electron acceptor compound, high molecular weight in a region which faces rare metal with the capacity transport polymers that carry may member is installed in the load lock.

In the present invention using polymerizable preferred that the hole-transporting compound of email widow, a web page or "polymerizable substituent", by the polymerization of the 2 molecules or more molecules to form bonds between a substituent capable of liberating upon group, hereinafter, . rapidly and to reduce a memory.

As said polymerizable substituent, the aforementioned of the present invention description of material organic electronic "polymerizable substituent" in the same, . similar to that of the a preferred embodiment.

Polymerizable substituents may, of applied is obtained by polymerization of the 2 molecules form a bisphenyl bond between or more molecules, coating film which serves to fasten the solubility change (curing) make. In order to vary the solubility coating film, 1 per molecule one or more polymerizable substituent is 2 is preferably not less.

In the present invention using the "hole-transporting compound", with the capacity transport in a region which faces including which is rare metal, hereinafter, . rapidly and to reduce a memory.

Said "in a region which faces transport with the capacity group" the, the ability to transport in a region which faces is if they have, specially but are not limited to, aryl amine, carbazole, thiophene which is desirably, for example, the general formula (1) ∼ (58) having moiety containing sequences represented by it is preferable that the.
