Description of the Related Art Generally, a relatively large-sized liquid crystal glass plate in which liquid crystal is sealed between an upper glass and a lower glass is cut into a plurality of liquid crystal plates along a predetermined cutting line. It is performed by a cutting blade while supplying a cutting fluid. In the work of cutting the liquid crystal glass plate, if a defective product is generated, there is a problem that the liquid crystal sealed in the liquid crystal storage portion is wasted. To avoid such waste, the liquid crystal glass plate may be cut in an empty state in which the liquid crystal is not sealed.However, a dirty cutting fluid flows in from a liquid crystal injection port provided in the liquid crystal storage portion, and the liquid crystal is cut after the cutting. Can no longer be injected. Therefore, the liquid crystal had to be sealed and cut first.

In the method, a liquid is supplied in place of the liquid crystal to the gap formed by the upper and lower glass sheets, and the liquid crystal glass plate is cut by a cutting blade while supplying a cutting liquid. Further, the liquid is pure water, and the cutting blade is a circular rotating blade.

Even if a defective product occurs, the liquid crystal is not sealed, so that waste of the liquid crystal can be reduced. After the cutting, if the liquid crystal is injected after removing the liquid by evaporation or the like, a target liquid crystal plate can be obtained.

Based on the alignment mark 5, a cut portion is precisely positioned and, as shown in FIG. While supplying the cutting fluid 7, the liquid crystal glass plate 1 is cut by a cutting blade 6 such as a circular rotary blade.

A liquid other than the liquid crystal such as pure water is filled in the inlet 3a.
The cutting operation is performed in a state filled with the liquid (there is no leakage due to the small inlet 3a). This is to prevent the cutting fluid supplied at the time of cutting from entering the liquid crystal housing 3. In other words, if the liquid crystal storage unit 3 is cut while empty, dirty cutting fluid will enter, and this is to be prevented.

塞ぐことで液晶収納部３内に液晶を封止する。Since the liquid crystal plate thus formed is still filled with liquid other than liquid crystal in the liquid crystal container 3, the liquid is removed and completely emptied. The liquid crystal is injected from the inlet 3a and the liquid crystal is sealed in the liquid crystal housing 3 by closing the injection port 3a.

ない。In this way, a desired liquid crystal plate can be obtained. However, even if the liquid crystal glass plate is cut and a defective product is generated due to glass breakage or the like, the liquid crystal is sealed in the liquid crystal plate. There is no need to waste expensive liquid crystal since it is only filled with liquid other than liquid crystal such as pure water.

要がある。In order to remove the liquid from the liquid crystal housing 3, the means for evaporating the liquid by heating, for example, is the simplest. A means for removing the liquid by suction is also considered. It is necessary to dry the moisture attached to the wall.
