## Abstract

A display device includes a lens array unit, a display unit which is configured such that a first substrate is attached to a second substrate that is disposed between the first substrate and the lens array unit, the display unit having a display area composed of matrix-arrayed pixels, a gap control layer which forms a predetermined gap between the display unit and the lens array unit, and a support member which fixes the display unit and the lens array unit on an outside of the display area of the display unit.

## Claims

### Claim 1

A display device comprising:
a lens array unit;
a display unit which is configured such that a first substrate is attached to a second substrate that is disposed between the first substrate and the lens array unit, the display unit having a display area composed of matrix-arrayed pixels;
a gap control layer which forms a predetermined gap between the display unit and the lens array unit; and
a support member which fixes the display unit and the lens array unit on an outside of the display area of the display unit.

### Claim 2 (depends on 1)

The display device according to claim 1, wherein the gap control layer is disposed on an inside surrounded by the support member.

### Claim 3 (depends on 1)

The display device according to claim 1, wherein the gap control layer is a spherical body or a columnar body.

### Claim 4 (depends on 1)

The display device according to claim 1, wherein the gap control layer is a light-transmissive resin film or glass plate.

### Claim 5 (depends on 1)

The display device according to claim 1, wherein the lens array unit includes a base body and a lens array layer which is provided on the base body and is opposed to at least the display area, and
the lens array unit is one of a lens array unit which is integrally formed of the base body and the lens array layer which are formed of a glass, a lens array unit which is formed by attaching the lens array layer of a resin to the base body of a glass via an adhesive, and a lens array unit which is formed by molding the lens array layer of a resin directly on the base body of a glass.

### Claim 6 (depends on 1)

The display device according to claim 1, wherein the display unit is a liquid crystal display panel.

### Claim 7 (depends on 1)

The display device according to claim 1, wherein the display unit includes, in the display area, a plurality of sub-pixels which constitute an effective pixel at a time of stereoscopic video display.

### Claim 8 (depends on 1)

The display device according to claim 1, wherein the support member is disposed between the first substrate of the display unit and the lens array unit.

### Claim 9 (depends on 1)

The display device according to claim 1, wherein the lens array unit includes a base body and a lens array layer which is provided on the base body and is opposed to the display unit, and
the support member is disposed between the first substrate of the display unit and the base body of the lens array unit.

### Claim 10 (depends on 1)

The display device according to claim 1, wherein the lens array unit includes a base body and a lens array layer which is provided on the base body and is opposed to the display unit, and
the support member is disposed between the first substrate of the display unit and the lens array layer of the lens array unit.
