Put the laminated glass original plate 1 into the vacuum chamber, and 10 -3 ~
Create a vacuum of about 10 -5 Torr and suck under vacuum for about 10 to 60 minutes. It is preferable to set the degree of vacuum in the gap between the original glass plates to 10 -1 Torr or less so that the sealing agent layer 3 can be bonded under atmospheric pressure, but the important point is that no large external pressure is applied when bonding the sealing agent layer 3. However, it is sufficient that the pressure is so low that the pressure difference between the pressure inside the plate gap and the pressure outside the plate is about 0.5 atm or more. after that,
The opening 6 of the ultraviolet curable resin layer 5 is sealed in vacuum with, for example, an ultraviolet curable resin 7, returned to atmospheric pressure, and then cured by ultraviolet rays. As a result, two original glass plates 1

The heating time is about 30 to 60 minutes. As a result, the sealant layer 3 is thermoset, and the two original glass plates 1 are adhered around each liquid crystal display panel 2. Then, the bonded glass original plate 1 is taken out from the heating chamber, and the glass original plate 1 is cut along the outer periphery of the sealant layer 3. As a result, a liquid crystal display panel can be obtained which can be divided into the respective liquid crystal display panels 2, the periphery of which is adhered by the sealant layer 3 and which is composed of a translucent substrate provided with electrode films facing each other with a constant gap.

The gap is evacuated and the periphery is sealed and heated under a pressure higher than the atmospheric pressure of the gap to fix them, so that any part is fixed in a uniformly pressurized state. Therefore, unevenness in the gap between the substrates of the liquid crystal display panel caused by unevenness in pressure does not occur, and a liquid crystal display device with uniform intervals and stable quality can be obtained.

Even if dust adheres to the outer surface of the translucent substrate, pressure will not concentrate on that part.Therefore, gap unevenness may occur at the dust adhering part or the translucent substrate may be damaged. Nonetheless, it contributes to the improvement of yield.

This contributes to cost reduction.
