Abstract

An organic luminescence device is constituted by an organic luminescence lamination structure comprising a pair of an anode and a cathode, and at least one organic compound layer disposed between the anode and the cathode, a hermetic sealing housing enclosing therein the organic luminescence lamination structure and blocking external air, and a drying agent disposed within the hermetic sealing housing. The drying agent comprises a compound represented by the following formula (1):

R—NCO  (1),

wherein R denotes a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted styryl group, a substituted or unsubstituted acyl group, or a substituted or unsubstituted heterocyclic group. The drying agent comprises the compound of the formula (1) in a polymerized form.

Claims

1. An organic luminescence device, comprising:

an organic luminescence lamination structure comprising a pair of an anode and a cathode, and at least one organic compound layer disposed between the anode and the cathode,

a hermetic sealing housing enclosing therein the organic luminescence lamination structure and blocking external air, and

a drying agent disposed within the hermetic sealing housing, wherein

the drying agent comprises a compound represented by the following formula (1);

2. A device according to claim 1, wherein the drying agent comprises the compound of the formula (1) in a polymerized form.

3. A device according to claim 1, wherein the drying agent comprises a mixture comprising the compound of the formula (1) and an inorganic compound.

4. A device according to claim 1, wherein the drying agent comprises a mixture comprising the compound of the formula (1) in a polymerized form and an inorganic compound.

5. A device according to claim 1, wherein the compound of the formula (1) is disposed on the organic luminescence lamination structure by vacuum deposition or coating.

6. A device according to claim 1, wherein the drying agent covers the organic luminescence lamination structure.

7. A device according to claim 6, further comprising a substrate having a supporting surface, wherein the organic luminescence lamination structure is disposed on the supporting surface, and wherein the drying agent covers a part of the supporting surface.

8. A device according to claim 6, further comprising a substrate having a supporting surface, wherein the organic luminescence lamination structure is disposed on the supporting surface, and wherein the drying agent is not disposed on the hermetic sealing housing.
