First claim
Opening claim text (preview).
What is claimed is: 1. A display device comprising: a substrate; an organic electric element located on the substrate; and an encapsulation part comprising a hygroscopic salt comprising a metal-organic framework comprising a cluster comprising zirconium and a positively charged organic ligand and an anion, and encapsulating the organic electric element; wherein the metal-organic framework is a UiO-66; and wherein the positively charged organic ligand includes methylated nitrogen atom of 2,5-pyridinedicarboxylic acid, and wherein the methylated nitrogen atom has a positive charge. 2. The display device according to claim 1 , wherein the encapsulation part further comprises a (meth) acrylate resin, and wherein the metal-organic framework is dispersed in the (meth) acrylate resin. 3. The display device according to claim 2 , wherein the encapsulation part has a haze of 10% or less. 4. The display device according to claim 2 , wherein the encapsulation part has a transmittance of 85% or more for light with a wavelength of 450 nm. 5. The display device according to claim 1 , wherein the organic ligand is a dicarboxylic acid comprising a heterocycle of C 2 -C 20 comprising at least one heteroatom selected from the group consisting of N, O, S and P, and at least one of the heteroatoms comprised in the heterocycle of C 2 -C 20 has a positive charge. 6. The display device according to claim 1 , wherein the positively charged organic ligand is a dicarboxylic acid comprising a heterocycle of 6 atoms comprising at least one heteroatom selected from the group consisting of N, O, S and P, wherein the at least one heteroatom has a positive charge, and wherein the two carboxyl groups of the dicarboxylic acids are in a para position with respect to each other. 7. The display device according to claim 1 , wherein the anion is consisting of BF 4 —, PF 6 or S 2 O 8 2− . 8. The display device according to claim 1 , wherein the hygroscopic salt is included 0.1 to 5 parts by weight.
