It is indicated by a broken line in (C). ). Especially, when the STN type liquid crystal is used as the liquid crystal, it is remarkable. First and second
If the liquid crystal injection hole is sealed while the distance between the substrates is wider than the permissible value, the liquid crystal panel will be in a state where the substrate spacing is deviated from the permissible value.

The portion located on aa can support the airtight holding member so as to bend slightly upward. The reason is as follows. In the case of the liquid crystal sealing device 30, it is preferable that a predetermined jig (details will be described later with reference to FIG. 4) is passed from the back surface side of the base plate 31a through the opening 31aa during the actual sealing work. , First and second airtight holding members 3
The airtight holding members 33 and 35 near the liquid crystal injection hole 21a are pushed upward by acting on the liquid crystal 3 and 35 (white arrows in FIG. 2; details will be described later). This is because if a part of the support member 39 is bent upward as described above, the above-mentioned pushing-up work by the jig can be easily performed. Further, the reason for performing the above-mentioned pushing-up work by the jig is to prevent the first and second airtight holding members 33 and 35 from coming off from the structure 21 due to the pressure inside the container 31. Furthermore, in order to facilitate the sealing work, the vicinity of the liquid crystal injection hole 21a is prevented from being covered with the first and second airtight holding members 33 and 35.
