摘要：PURPOSE:To hold an air bubble in a cell where the air bubble is hidden from a display surface and to prevent the production of a defective due to the air bubble, by providing an air-bubble holding space where the air bubble in liquid crystal is stored. CONSTITUTION:The liquid crystal 3 is injected into the part of a liquid-crystal cell 1 encircled with a seal material 2 through an injection hole 4, and the air- bubble holding space 5 formed of the same seal material 2 is provided on the part opposite to the injection hole 4. This space 5 is not placed in the display surface displayed by segment patterns 7, but provided where it is hidden from a display window 8. Then, the liquid crystal 3 is injected by a vacuum injecting method. Namely, the liquid-crystal cell 1 is evacuated by a vacuum pump and the injection hole 4 is put in a liquid-crystal tank to charge the liquid crystal 3. Air bubbles in the liquid crystal are pressed up to enter the air-bubble holding space 5, and the liquid-crystal injection hole 4 is sealed with epoxy resin, etc.
