## Abstract

According to one embodiment, an apparatus for manufacturing a display device, includes: a first holding section configured to hold a first substrate; a second holding section configured to hold a second substrate; a turning section configured to turn the first holding section such that the first substrate and the second substrate face each other; a support section configured to support the first holding section after the turning; an adjustment section; and an elevation section. The adjustment section is provided at an upper end of the support section and is configured to adjust a distance between the first holding section after the turning and the upper end of the support section. The elevation section is configured to elevate the second holding section and attach the first substrate and the second substrate via an adhesive layer.

## Claims

### Claim 1

An apparatus for manufacturing a display device, comprising:
a first holding section configured to hold a first substrate;
a second holding section configured to hold a second substrate;
a turning section configured to turn the first holding section such that the first substrate and the second substrate face each other;
a support section configured to support the first holding section after the turning;
an adjustment section provided at one end of the support section and configured to adjust a distance between the first holding section after the turning and the one end of the support section;
an elevation section configured to elevate the second holding section and attach the first substrate and the second substrate via an adhesive layer; and
a floating section provided between the turning section and a first turning shaft, the floating section being configured such that the first holding section is displaceable with respect to the first turning shaft via the turning section, the floating section including a shaft section, a plate section, and at least one elastic section, the shaft section being a section of a second shaft and being provided on the first turning shaft of the turning section, the shaft section being inserted through one end side of the plate section, another end side of the plate section being provided on the first holding section, and the at least one elastic section is provided at a position between an end portion of the shaft section and one end side of the plate section along the shaft section.

### Claim 2 (depends on 1)

The apparatus according to claim 1, further comprising a pressing section figured to press the first holding section after the turning toward the support section.

### Claim 3 (depends on 2)

The apparatus according to claim 2, wherein the pressing section has a claw configured to press the first holding section.

### Claim 4 (depends on 2)

The apparatus according to claim 2, wherein the support section and the pressing section cooperate to maintain a position of the first holding section after the turning.

### Claim 5 (depends on 1)

The apparatus according to claim 1, wherein the support section is provided in plural, and
the plurality of support sections are provided near four corners of the first holding section after the turning.

### Claim 6 (depends on 1)

The apparatus according to claim 1, wherein the adjustment section has at least one of a screw mechanism provided at the one end of the support section and a spacer provided at the one end of the support section.

### Claim 7 (depends on 1)

The apparatus according to claim 1, wherein
the at least one elastic section includes a set of elastic sections provided to sandwich the plate section.

### Claim 8 (depends on 7)

The apparatus according to claim 7, wherein the plate section is movable along the shaft section.

### Claim 9 (depends on 1)

The apparatus according to claim 1, further comprising:
a measurement detector configured to measure a thickness dimension of the first substrate held on the first holding section and a thickness dimension of the second substrate held on the second holding section; and
a controller configured to control the elevation section such that the thickness dimension of the adhesive layer is within a predetermined range based on the thickness dimension of the first substrate and the thickness dimension of the second substrate.

### Claim 10 (depends on 1)

The apparatus according to claim 1, wherein the adhesive layer comprises an ultraviolet ray curing resin,
further comprising a radiation section configured to radiate ultraviolet rays to a partial region of the adhesive layer.

### Claim 11 (depends on 10)

The apparatus according to claim 10, wherein the radiation section radiates the ultraviolet rays to the partial region of the adhesive layer via a hole section formed in the first holding section.

### Claim 12 (depends on 1)

The apparatus according to claim 1, further comprising a position controller configured to perform position control of the second holding section.

### Claim 13 (depends on 12)

The apparatus according to claim 12, further comprising an imager configured to image recognition sections formed on the first substrate and the second substrate,
wherein the position controller performs the position control on the second holding section based on information from the imager.
