ことがあげられる。A first problem of the prior art 1 is that a gap varies between the liquid crystal display cells 1. The reason is that a plurality of liquid crystal display cells 1
And the cushion material 26 are alternately laminated, the pressure applied to each cushion material 26 is different, and it is difficult to uniformly control the gap of each liquid crystal display cell 1.

れる。As a second problem, there is a problem in the feasibility of device creation. If the manufacturing accuracy (dimensions, hardness, elasticity count, etc.) of the solid material 27 having elasticity itself varies from one cushion material 26 to another, the pressure applied to the liquid crystal display cell 1 also varies. The gap value of the liquid crystal display cell 1 also varies.

とがあげられる。The first problem of the conventional example 2 is that the feasibility of device creation is problematic. The reason for this is that the accuracy (dimensions, hardness, elasticity count, etc.) of the hollow pressurizing body 34 made of an elastic body is different from that of the hollow pressurizing body 34 made of an individual elastic body.
If the liquid crystal display cell 1 varies, the gap value varies between the liquid crystal display cells 1. As a second problem, there is a problem in production. The reason is that the pressurizing member 34 having a hollow structure made of an elastic body comes into direct contact with the display area of the liquid crystal display cell 1, so that the cell 1 is broken by glass debris or the like or the surface of the cell 1 is contaminated. There are things.

However, the first problem is that air leakage occurs and the liquid crystal display cell 1 Cannot be performed stably. The reason is that the O-rings 37 and 38 are installed outside the display area of the liquid crystal display cell 1, that is, near the outer shape of the liquid crystal display cell 1, and the O-rings 37.3 and 30.3 are sufficient for air leak.
8 cannot be obtained. If an air leak occurs, a desired pressure cannot be applied to the liquid crystal display cell 1, the gap of the liquid crystal display cell 1 does not reach a desired value, and a display problem occurs.

ギャップ値がばらついてしまうことがあげられる。As a second problem, there is a problem that a plurality of sheets cannot be processed. The reason for this is that in the case of processing a plurality of sheets (lamination processing), the sealing position is likely to shift for each layer, which causes air leakage, which is the first problem, and the applied pressure varies between the liquid crystal display cells 1; The gap value between 1 may vary.

実現できる為である。The first effect of the present invention described above is that gas leakage does not occur. This allows
The uniform gap control of the liquid crystal display cell 1 can be performed. The reason is that the O-rings 9 and 12 are set in the display area, so that the sealing width can be made wider than in the conventional case, and as shown in FIG.
Even when a pressure of 2 cm 2 was applied, the pressure leaked at 0.3 kg / cm 2 , and a further pressing force could not be applied, so that the conventional technology could not reach the target gap value of 5.0 μm (up to 5.0 μm). On the other hand, according to the present invention, since the present invention is excellent in leak resistance, the pressure applied to the cylinder is applied to the liquid crystal display cell 1 as it is, and the target gap of 5.0 μm can be realized.

である。The second effect is that a plurality of sheets can be processed without causing a gas leak. Thereby, uniform gap control of the liquid crystal display cell 1 can be performed by processing a plurality of sheets. The reason is that the O-rings 9 and 12 are set in the display area,
This is because the sealing width can be made wider than before, and even if the superposition of the liquid crystal display cell 1 and the non-contact pressing jig 2 is shifted, the leakage resistance is excellent and the multi-sheet processing can be endured.

The reason is that if glass dust or the like is mixed in contact with the display area, the substrate is cracked due to the pressing of the jig. However, in the present invention, the contact portion is only an O-ring and is extremely small.
