Manufacturing method of liquid crystal display panel and manufacturing apparatus of liquid crystal display panel

A manufacturing method of a liquid crystal display panel, comprising:

• a sealant arranging step of arranging a sealant on a main surface of one of or each of two substrates to be bonded to each other;
• a liquid crystal dropping step of dropping liquid crystal on one of said two substrates wherein each of the two substrates has an alignment film;
• and
• a bonding step of bonding said two substrates to each other, wherein said method further includes:
• to be performed prior to said sealant arranging step, a deaerating step of arranging in a pressure-reduced atmosphere at least a substrate on which said sealant is to be arranged out of said two substrates, such substrate being placed in the pressure reduced atmosphere with the alignment film exposed;
• and
• to be performed prior to said bonding step, a releasing step of releasing said pressure-reduced atmosphere by an inert gas;
• wherein said releasing step is performed prior to said sealant arranging step and said sealant arranging step is performed in an inert gas atmosphere provided by the releasing step.
