止方法である。(d) Means for solving the problems This invention provides a frame-shaped main seal pattern having an injection hole formed by cutting out a part between two glass substrates, and a frame-shaped main seal pattern having an injection hole intermittently formed between two glass substrates. After forming an auxiliary seal pattern with a sealing material and injecting a predetermined volume of liquid crystal between the °C glass substrates through the injection hole, the glass substrates are heated while being pressurized from both sides to form a main seal pattern. This is a method for sealing a liquid crystal injection hole in a liquid crystal cell, which is characterized in that the injection hole is sealed by curing the injection hole and extending and bridging the auxiliary seal pattern with each other.
