い。The filled liquid crystal layer expands and contracts due to environmental temperature fluctuations,
The display characteristics and life characteristics of the liquid crystal cell deteriorate. That is, when the environmental temperature rises, the liquid crystal layer thermally expands, causing the central portion of the liquid crystal cell to swell. The sealing material around the liquid crystal cell is usually an organic adhesive such as 4Ki, which has already hardened before filling the liquid crystal, so even if the center of the liquid crystal cell swells due to a temperature rise of 85 degrees Celsius, the surrounding seal will remain intact. The thickness of the stop does not change between friends.

損なうことになる。However, if this liquid crystal cell is kept under a product term of 85°C for a long time (e.g. 1000 hours) or kept under thermal cycles (e.g. -40°C 1 hour + 85°C 1 hour heat cycle 20 times). In this case, the sealing part cannot withstand the internal pressure accompanying the expansion of the liquid crystal within the cell, and the thickness of the sealing part increases irreversibly. In such a state, when the temperature is returned to room temperature, the liquid crystal will shrink or the thickness of the sealing portion will increase to +11, resulting in uneven thickness between the center and the periphery of the liquid crystal cell. As a result, in the NWi liquid crystal cell, a colored pattern due to interference fringes is produced, and in the GH11 liquid crystal cell, the display color becomes uneven, and the characteristics as a display cell are significantly impaired.

とが提案されている。しかし単に非充填部を設けるだけ
では、この非充填部と表示部が重なったとIKは表示機
能が損われるという不都合があった。As a solution to the above problem, it has been proposed to leave a portion in the liquid crystal cell that is not filled with liquid crystal to absorb the volumetric expansion of the liquid crystal. However, simply providing a non-filled portion has the disadvantage that the display function of the IK is impaired if the non-filled portion overlaps with the display portion.

There is an empty space in the chamber that is not filled with liquid crystal, and a cell chamber for the first cell and a second cell chamber.
The 0 cell chambers are connected by a low conductance connecting passageway that allows movement of liquid crystal.

Since it can be partially absorbed, deterioration of display characteristics due to temperature fluctuations is reliably prevented. The first cell chamber in which the display section is located and the second cell chamber in which the gap remains are connected by a low-conductance connecting passage, which prevents the display section and the gap from overlapping each other. It does not impair the display function.

し、注入口11部を液晶で覆ってもよい。11 cells are glued together to form a 10th cell chamber Ah- and a second cell chamber J+B1. At that time, a part of the sealing material IJ is cut out to provide an injection port 11 for filling the liquid crystal. Next, the entire % liquid crystal cell is placed in a vacuum container, and the air inside the liquid crystal cell is exhausted to evacuate each chamber. Next, while holding the vacuum tube inside the liquid crystal cell, liquid crystal is applied to cover the injection port 11. Generally, the liquid crystal material used in these display cells has a higher viscosity than liquids such as water, so it is necessary to apply the material in an amount equivalent to the internal volume of the liquid crystal cell. In reality, you can apply liquid crystal with a cell content IU 2 times 11 degrees, or you can immerse it in a container with a liquid crystal reservoir with the injection port 11 facing downward in a vacuum chamber, and cover the injection port 11 with liquid crystal. .

to fill up. This flow into the second cell chamber BSeB snow flows into the connecting passage 151. between this and the first cell chamber A.
1B is a narrow passageway, and the conductance of the ninth cell flowing through it is low, so that it first empties after the first cell chamber A is filled. Second cell room Bl+! Injection of liquid crystal into 1 g is shown in Figure 1 (
As shown in b), the tip of the liquid crystal 12 is connected to the connecting passage 151.
Stop m1h when it reaches the end. and,
Wipe off the liquid crystal applied to the outside of the injection port 11 with a cloth, etc.
Immediately, a quick-drying sealant is applied to the outside of the injection port 11, and a small amount of this is introduced into the cell to close the injection port 1r. As a result, the second cell i! ! A void is left in B1+B*.

e 110 It is absorbed by the air, and the thickness does not change due to IF. Generally, the volumetric thermal coefficient of liquid crystal is approximately I

止される。Therefore, as mentioned above, if the temperature continues to rise to about 85°C for a long time, if the liquid crystal is completely filled, the display characteristics will change due to irreversible thickness fluctuations in the liquid crystal cell O. As a result, the operating temperature range is limited to -5℃ to 55℃ and 11 degrees.In contrast, according to this It appears that it can be used without causing any deterioration. Since the first cell chamber containing the display section and the third cell chamber having the void are connected by a low-conductance connecting passage, the void is always connected to the inside of the cell with a double-layered structure. The condition is maintained, and the situation where the gap overlaps with the display section and impairs the display function is prevented.

A low humemectance O is passed between the eighth cell chamber having a void.
Since they are connected by a connecting passage, the sky IIw always reverberates inside the first cell chamber, which contributes to the display function.It does not enter the first cell chamber, and the display function is not impaired. .
