## Abstract

There is provided an organic light emitting display device including a first substrate; an organic light emitting unit formed on the first substrate; a second substrate disposed on the organic light emitting unit; and an adhesive unit for adhering the first substrate and the second substrate to each other, wherein the adhesive unit includes a sealant, and particles that are arranged in the sealant so as to block penetration of external impurities. There is further provided a method of manufacturing the organic light emitting display device.

## Claims

### Claim at position 1

1-11. (canceled)

### Claim 12

A method of manufacturing an organic light emitting display device, the method comprising:
forming an organic light emitting unit on a first substrate;
coating an adhesive unit on a second substrate;
adhering the first substrate and the second substrate to each other so that the adhesive unit surrounds the organic light emitting unit;
making an application of an electric field or a magnetic field to the adhesive unit; and
hardening the adhesive unit so as to adhere the first substrate and the second substrate to each other.

### Claim 13 (depends on 12)

The method of claim 12, wherein the adhesive unit comprises a sealant and particles that are dispersed in the sealant.

### Claim 14 (depends on 13)

The method of claim 13, wherein the particles are polarizable.

### Claim 15 (depends on 14)

The method of claim 14, wherein the applying application of the electric field or the magnetic field comprises:
applying the electric field lines or the magnetic field lines in a direction generally perpendicular to the first substrate and the second substrate; and arranging the particles in the direction of the electric field lines or the magnetic field lines.

### Claim 16 (depends on 15)

The method of claim 15, wherein the particles form a plurality of chains that are each arranged in a direction generally perpendicular to the first substrate and the second substrate.

### Claim 17 (depends on 14)

The method of claim 14, wherein the particles are linearly arranged end to end between the first substrate and the second substrate.

### Claim 18 (depends on 14)

The method of claim 14, wherein the particles comprise a polarizable organic material.

### Claim 19 (depends on 18)

The method of claim 18, wherein the organic material is one selected from the group consisting of polyaniline, polypyrrole, poly(p-phenylene), poly naphthalene quinine radicals, poly acene quinone radicals, poly phenylenediamine, and polythiophene.

### Claim 20 (depends on 14)

The method of claim 14, wherein the particles comprise a polarizable inorganic material.

### Claim 21 (depends on 20)

The method of claim 20, wherein the inorganic material is one selected from the group consisting of silica gel, silica, zeolite, and a mesoporous material.

### Claim 22 (depends on 13)

The method of claim 13, wherein the sealant comprises an insulating material.

### Claim 23 (depends on 22)

The method of claim 22, wherein the sealant comprises one selected from the group consisting of silicon, epoxy, and acryl.

### Claim 24 (depends on 12)

The method of claim 12, wherein the hardening of the adhesive unit is performed by heating the adhesive unit.

### Claim 25 (depends on 12)

The method of claim 12, wherein the hardening of the adhesive unit is performed by applying ultraviolet rays to the adhesive unit.

### Claim 26 (depends on 12)

The method of claim 12, wherein the hardening of the adhesive unit is performed when the electric field or the magnetic field is applied to the adhesive unit.
