## Abstract

An example display apparatus, comprising a display panel with one surface on which an image is displayed, a light guide plate disposed to face the other surface of the display panel, an optical sheet interposed between the display panel and the light guide plate, and a spacer which is sandwiched between the display panel and the light guide plate to secure a space for the optical sheet, wherein the spacer is adhered to the light guide plate and the display panel.

## Claims

### Claim at position 1

1-10. (canceled)

### Claim 11

A display apparatus, comprising a display panel with one surface on which an image is displayed, a light guide plate disposed to face the other surface of the display panel, an optical sheet interposed between the display panel and the light guide plate, and a spacer which is sandwiched between the display panel and the light guide plate to secure a space for the optical sheet,
wherein the spacer is adhered to the light guide plate and the display panel.

### Claim 12 (depends on 11)

The display apparatus according to claim 11, wherein the optical sheet has a peripheral edge provided with a convex part, and
the spacer is provided so as to surround the optical sheet and has a void in which the convex part is inserted.

### Claim 13 (depends on 11)

The display apparatus according to claim 11, wherein the spacer includes a plurality of layers laminated in a direction in which the display panel and the light guide plate face each other.

### Claim 14 (depends on 11)

A method of manufacturing the display apparatus according to claim 11, comprising the processes of:
dropping solidifiable liquid on the light guide plate;
placing the display panel on the dropped liquid; and
solidifying the liquid after placing the display panel,
wherein the spacer is formed by solidification of the liquid.

### Claim 15 (depends on 11)

A method of manufacturing the display apparatus according to claim 11, comprising the processes of:
dropping a molten hot-melt adhesive on the light guide plate; and
placing the display panel on the dropped adhesive before the adhesive is solidified;
wherein the spacer is formed by solidification of the adhesive.

### Claim 16 (depends on 11)

A method of manufacturing the display apparatus according to claim 11, comprising the processes of:
dropping solidifiable liquid on the light guide plate;
stacking the optical sheet on the light guide plate;
placing the display panel on the dropped liquid; and
solidifying the liquid after placing the display panel,
wherein the spacer is formed by solidification of the liquid.

### Claim 17 (depends on 11)

A method of manufacturing the display apparatus according to claim 11, comprising the processes of:
forming the spacer by dropping solidifiable liquid on the light guide plate and solidifying the liquid; and
stacking the optical sheet on the light guide plate after the forming process.

### Claim 18 (depends on 13)

A method of manufacturing the display apparatus according to claim 13, comprising:
a dropping process that drops solidifiable liquid on the light guide plate;
a solidifying process that solidifies the liquid; and
a stacking process that stacks the optical sheet on the light guide,
wherein the plurality of layers are formed by a repeat of the dropping process and the solidifying process, and the stacking process is performed after forming a part of the plurality of layers during the repeat of the dropping process and the solidifying process.

### Claim 19 (depends on 13)

A method of manufacturing the display apparatus according to claim 13, comprising:
a dropping process that drops solidifiable liquid on the light guide plate;
a solidifying process that solidifies the liquid;
a stacking process that stacks the optical sheet on the light guide; and
a placing process that places the display panel on the dropped liquid,
wherein the plurality of layers are formed by a repeat of the dropping process and the solidifying process, the stacking process is performed after forming a part of the plurality of layers during the repeat of the dropping process and the solidifying process, and the placing process is performed between the stacking process and solidification of the lastly dropped liquid during the repeat of the dropping process and the solidifying process.

### Claim 20

A method of manufacturing a display apparatus comprising a display panel with one surface on which an image is displayed, a light guide plate disposed to face the other surface of the display panel, an optical sheet interposed between the display panel and the light guide plate, and a spacer which is sandwiched between the display panel and the light guide plate to secure a space for the optical sheet, the method comprising:
forming the spacer by dropping solidifiable liquid on the light guide plate and solidifying the liquid.
