Definitions
- an organic material doped with an alkali metal used as a material for the electron transport layer and the electron injection layer has a problem that the alkali metal has high reactivity and easily becomes a hydroxide. For this reason, in the manufacturing process of the light emitting device, strict process control must be performed so that the organic material doped with an alkali metal or the formed thin film does not react with moisture or other impurities in the air.
- the sealing of the light emitting element or the light emitting device must be completed so that outside air leaks into the manufactured light emitting element and does not react with water vapor or the like. Also, it was difficult to manufacture a light-emitting element having a sufficiently long life.
- an EL element using a material containing empty fullerenes such as C 1 and C 2 as an electron transporting layer is known (Patent Document 1).
- empty fullerenes have a problem that the luminous efficiency is not high because the electron affinity is relatively small and the electron injection efficiency is poor.
- the present invention (1) provides a light-emitting element including an anode, a light-emitting layer, and a cathode, wherein an electron-injection layer and / or an electron-transport layer is interposed between the cathode and the light-emitting layer.
- a light-emitting element including an anode, a light-emitting layer, and a cathode, wherein an electron-injection layer and / or an electron-transport layer is interposed between the cathode and the light-emitting layer.
- / or the electron transport layer is an organic material doped with alkali metal-encapsulated fullerenes or alkali metal-encapsulated fullerenes.
- FIG. 2 is a cross-sectional view of a light emitting device according to a second specific example.
- An anode 10, a hole injection layer 11, a hole transport layer 12, a light emitting layer 13, an electron transport layer 14, an electron injection layer 15, and a cathode 16 are sequentially laminated on a plastic substrate 9.
- a plastic substrate such as PET
- the cost of light emitting devices can be reduced.
- a positive drive voltage is applied to the anode 10 with respect to the cathode 16 by an external drive circuit, the electrons injected from the anode 16 are recombined with the holes S injected from the anode 10 and the light emitting layer 13.
- the light emitting layer 13 emits light.
- FIG. 3 is a cross-sectional view of a light emitting device according to a third specific example.
- the light-emitting element according to the third specific example includes an anode 18, a hole injection layer 19, a hole transport layer 20, a light-emitting layer 21, an electron transport layer 22, an electron injection layer 23, and a cathode 24 on a glass substrate 17. They are formed by being sequentially laminated.
- FIG. 6 is a sectional view of a light emitting device according to a sixth specific example.
- the light emitting element according to the sixth specific example is an active matrix driven light emitting element in which each light emitting element has a driving element, and uses SIT as the driving element.
- a source electrode 39, a semiconductor layer 40, a hole injection layer 42, a hole transport layer 43, a light emitting layer 44, an electron transport layer 45, an electron injection layer 46, and a drain electrode 47 are sequentially laminated on a glass substrate 38. Is formed.
- the gate electrode 41 is arranged in a comb shape in the semiconductor layer 40.
- a transparent glass substrate (Coating 1713, 30 mm X 30 mm, thickness 0.8 mm) was prepared, and a thin film made of ITO was deposited on a glass substrate by sputtering to a thickness of 340 A to form an anode.
- a thin film made of Tokyo Kasei copper phthalocyanine (trade name: P1005) was deposited on the anode by a vapor deposition method to a thickness of 10 A to form a hole injection layer.
- a thin film made of Aldrich NPD (trade name: 55,669-6) was deposited at a thickness of 1000 A by a vapor deposition method to form a hole transport layer.
