Patent ID: 7295280

Claim:
A method of manufacturing a one drop fill liquid crystal display panel, comprising the steps of: providing a first substrate comprising a first central region and a first peripheral region, wherein a color pixel area and a black matrix area are positioned on the first central region; providing a second substrate comprising a second central region and a second peripheral region, wherein the second central region and the second peripheral region are positioned opposite to the first central region and the first peripheral region respectively; forming a first sealant area on the first peripheral region at an outside of the black matrix area, wherein the first sealant area is separated from the black matrix area by a first predetermined space in a range of from 0 to 10 mm; dispersing at least one drop of a liquid crystal on the second central region; superposing the first substrate and the second substrate under a condition of reduced ambient air pressure; and curing the first sealant area by applying a curing light from a side of the first substrate and through the first substrate to harden the first sealant area without light shielding resulting from the black matrix area, wherein a wavelength of the curing light is about between 300 nm and 500 nm, wherein the first sealant area is heated to a temperature range of 100° C. to 150° C., and wherein a heating time of curing the first sealant area keeps in a range of from 0.5 to 3 hours.
