ABSTRACT:
A method of manufacturing a liquid crystal panel, in which a first seal for surrounding a display area is formed on one of a pair of substrates opposite to each other; a second seal for forming a reduced-pressure area is formed outside the display area; a liquid crystal material is dropped in a reduced-pressure state; thereafter, the other substrate is adhered thereto; and the first and second seals are hardened while pushing the substrates from the outsides thereof in an atmospheric pressure state, thus sealing the liquid crystal material. A dropped area of the liquid crystal material is defined satisfy: 2.5b≦a≦5b where “a” is an interval between an internal peripheral portion of the first seal and an external peripheral portion, and “b” is an interval between an external peripheral portion of the first seal and an internal peripheral portion of the second seal.
