## Abstract

There is disclosed a display device comprising a display module, an outer case in which the display module is mounted and defining an internal space which is closed airtight from the outside, and an inner case coupled to the display module, wherein the inner case which partitions off the internal space into a first closed space having a rear surface of the display module exposed thereto and a second closed space having a front surface of the display module exposed thereto, and the first closed space is surrounded by the second closed space with respect to one cross section.

## Claims

### Claim 1

A display device comprising:
a display module;
an outer case in which the display module is mounted and defining an internal space which is closed airtight from the outside;
an inner case coupled to the display module,
wherein the inner case which partitions off the internal space into a first closed space having a rear surface of the display module exposed thereto and a second closed space having a front surface of the display module exposed thereto, and
wherein the first closed space is surrounded by the second closed space with respect to one cross section; and
a first open hole configured to allow a first region of an outer surface of the outer case and a second region of an outer surface of the inner case adjacent to the first region to form an outer passage,
wherein the first open hole passes between the first closed space and the second closed space.

### Claim 2 (depends on 1)

The display device of claim 1, wherein the outer case comprises a plurality of outer surfaces which are toward different directions, respectively, and
an inlet of the first open hole is formed in one of the outer surfaces and an outlet of the first open hole is formed in another one of the outer surfaces.

### Claim 3 (depends on 1)

The display device of claim 1, further comprising:
a partition bracket provided between the first region and the second region and configured to partition off the inlet and the outlet of the first open hole,
wherein an inlet of the first open hole is formed in the first region of the outer case and an outlet of the first open hole is formed in the second region adjacent to the first region.

### Claim 4 (depends on 3)

The display device of claim 3, wherein the partition bracket allows the first open hole to form a ‘⊏’-shaped passage.

### Claim 5 (depends on 3)

The display device of claim 3, wherein the partition bracket comprises a branched bracket configured to widen an angle between a direction toward the inlet and a direction toward the outlet of the first open hole.

### Claim 6 (depends on 1)

The display device of claim 1, wherein the first open hole comprises a guide bracket configured to bend air flow of an outer passage.

### Claim 7

A display device comprising:
a display module;
an outer case in which the display module is mounted and defining an internal space which is closed airtight from the outside;
an inner case coupled to the display module,
wherein the inner case which partitions off the internal space into a first closed space having a rear surface of the display module exposed thereto and a second closed space having a front surface of the display module exposed thereto; and
a second open hole configured to allow a third region of an outer surface of the outer case to form an outer passage,
wherein the second open hole is surrounded by the first closed space and the first closed space forms a closed loop.

### Claim 8

A display device comprising:
a display module;
an outer case in which the display module is mounted and defining an internal space which is closed airtight from the outside;
an inner case coupled to the display module,
wherein the inner case which partitions off the internal space into a first closed space having a rear surface of the display module exposed thereto and a second closed space having a front surface of the display module exposed thereto; and
a third open hole configured to allow a fourth region of an outer surface of the outer case to form an outer passage,
wherein the third open hole comprises:
a first heat radiation portion configured to form one of a rear surface of the outer case;
a second heat radiation portion spaced apart from the first heat radiation portion; and
a connecting portion configured to connect the first heat radiation and the second heat radiation portion with each other in one region to connect the outer passage as one continuous passage.

### Claim 9 (depends on 8)

The display device of claim 8, wherein the second closed space forms a closed loop which circulates around a front surface space of the display module and a spaced gap between the first heat radiation portion and the second heat radiation portion.
