Patent ID: 7553392

Claim:
A method of manufacturing a liquid crystal display device using a one drop fill method of performing liquid crystal injection by dropping liquid crystal on a first substrate formed with a seal material, causing a liquid crystal dropping side of the first substrate to face an opposite substrate, laminating the substrates in a vacuum, and restoring an atmospheric pressure, the method comprising the step of; manufacturing a reference liquid crystal display panel for measuring a cell gap width using a one drop fill method using a predetermined reference quantity; determining a variation that exists in a distribution of a cell gap width of the reference liquid crystal display panel for measuring a cell gap width within an area formed by a seal material; controlling a dropping quantity of each drop of the liquid crystal on the first substrate, so that a distribution of a total quantity of the liquid crystal between the first substrate and the opposite substrate varies with the variation in the distribution of the cell gap width, while the total quantity of the liquid crystal between the first substrate and the opposite substrate remains constant at the predetermined reference quantity, wherein the distribution of the cell gap width is generated by degree of parallelism between facing surfaces of an upper plate and a lower plate of a substrate laminating apparatus or by distortion occurring on at least one of the first substrate and the opposite substrate of the reference liquid crystal display panel for measuring a cell gap width.
