Abstract:
A manufacturing method of a liquid crystal display panel includes: 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 the two substrates; and a bonding step of bonding the two substrates to each other, wherein the method further includes: to be performed prior to the liquid crystal dropping step, a deaerating step of arranging in a pressure-reduced atmosphere at least a substrate on which the liquid crystal is to be dropped out of the two substrates; and, to be performed prior to the bonding step, a releasing step of releasing the pressure-reduced atmosphere by an inert gas.
