## Abstract

Provided is a frit sealing system for attaching a first substrate and a second substrate by using a frit. The frit sealing system includes a laser irradiation member configured to irradiate a laser on the frit between the first substrate and the second substrate, and a pressurization member on the second substrate, the pressurization member being configured to apply pressure to the second substrate during the irradiation of the laser, the pressurization member including base, and an elastic portion connected to the base and contacting the second substrate.

## Claims

### Claim 1

A frit sealing system for attaching a first substrate and a second substrate by using a frit, the frit sealing system comprising:
laser irradiation member configured to irradiate a laser on the frit between the first substrate and the second substrate; and
a pressurization member on the second substrate, the pressurization member being configured to apply pressure to the second substrate during the irradiation of the laser, the pressurization member including:
a base, and
an elastic portion connected to the base and contacting the second substrate, a first surface of the base facing the elastic portion,
wherein end portions of the elastic portion are connected to opposite ends of the first surface of the base, and a center portion of the elastic portion extends between the end portions of the elastic portion to be parallel to the second substrate, a distance from the first surface of the base to a first surface of the center portion being permanently larger than a distance from the first surface of the base to first surfaces of the end portions, the first surfaces of the center portion and end portions of the elastic portion facing the second substrate, and
wherein the laser passes through the base, the elastic portion, and the second substrate to be irradiated on the frit.

### Claim 2 (depends on 1)

The frit sealing system as claimed in claim 1, wherein:
the center portion of the elastic portion contacts the second substrate, and
the pressurization member further comprises a space between the first surface of the base and the center portion of the elastic portion, the space including fluid.

### Claim 3 (depends on 2)

The frit sealing system as claimed in claim 2, wherein, when the fluid fills the space between the base and the elastic portion, the elastic portion is configured to apply pressure to the second substrate such that injection of the fluid into the space causes the pressure to be applied to the second substrate by the elastic portion.

### Claim 4 (depends on 2)

The frit sealing system as claimed in claim 2, wherein the elastic portion includes material that transmits the laser.

### Claim 5 (depends on 2)

The frit sealing system as claimed in claim 2, further comprising a transmission portion connected to the elastic portion, the transmission portion being configured to transmit the laser.

### Claim 6 (depends on 5)

The frit sealing system as claimed in claim 5, wherein the transmission portion overlaps the frit between the first substrate and the second substrate.

### Claim 7 (depends on 6)

The frit sealing system as claimed in claim 6, wherein each of the fit and the transmission portion has a closed-curve pattern.

### Claim 8 (depends on 5)

The frit sealing system as claimed in claim 5, wherein the laser is configured to pass through the base, the fluid, the transmission portion, and the second substrate to be irradiated on the frit.

### Claim 9 (depends on 5)

The frit sealing system as claimed in claim 5, wherein the transmission portion includes a plurality of transmission portions.

### Claim 10 (depends on 2)

The frit sealing system as claimed in claim 2, wherein the fluid is air.

### Claim 11 (depends on 1)

The frit sealing system as claimed in claim 1, wherein:
a second surface of the center portion of the elastic portion is flat and positioned flush against the first surface of the base, and the first surface of the center portion of the elastic portion is opposite the first surface and contacts the second substrate, and
the elastic portion is configured to apply pressure to the second substrate while the pressurization member is moving in a vertical direction.

### Claim 12 (depends on 1)

The frit sealing system as claimed in claim 1, wherein the elastic portion includes a material that transmits the laser.

### Claim 13 (depends on 12)

The frit sealing system as claimed in claim 12, wherein the elastic portion includes a rubber material.

### Claim 14 (depends on 13)

The frit sealing system as claimed in claim 13, wherein the center portion is flush against and in direct contact with the entire second substrate, the elastic portion maintaining direct and constant contact with the base.

### Claim 15 (depends on 1)

The frit sealing system as claimed in claim 1, further comprising a transmission portion connected to the elastic portion and configured to transmit the laser.

### Claim 16 (depends on 15)

The frit sealing system as claimed in claim 15, wherein the transmission portion is positioned within openings in the elastic portion, the transmission portion overlapping the frit between the first substrate and the second substrate.

### Claim 17 (depends on 16)

The frit sealing system as claimed in claim 16, wherein the frit and the transmission portion are disposed to have a closed-curve shape.

### Claim 18 (depends on 15)

The frit sealing system as claimed in claim 15, wherein the laser passes through the base, the transmission portion, and the second substrate and is irradiated on the frit.

### Claim 19 (depends on 15)

The frit sealing system as claimed in claim 15, wherein the transmission portion includes a plurality of transmission portions.

### Claim 20 (depends on 1)

The frit sealing system as claimed in claim 1, wherein a first surface of the elastic portion facing the second substrate has a curved shape, the curved shape including curved portions connecting the end portions to the center portion.
