The liquid crystal display device comprises a pair of spaced parallel insulating substrates, at least one of which being transparent, opposing electrodes formed on the inner surfaces of the substrates, a peripheral sealing member for sealing the peripheries of the substrates and provided with a filling port for filling a liquid crystal into a space between the substrates, a metal layer formed across the full width of the side surfaces of the substrates sandwiching the sealing member surrounding the filling port, and a solder layer formed on the metal layer to seal the filling port. The solder layer has an amount of 0.1 to 1.2mg/mm.sup.2, and is formed by applying a molten solder ball having a predetermined weight.
A liquid crystal display device comprising a pair of parallel insulating substrates spaced a predetermined spacing, at least one of the substrates being transparent, opposed electrodes formed on the opposing surfaces of said substrates, a peripheral sealing member for sealing the peripheries of said substrates for defining a space for accommodating a liquid crystal, means for defining a filling port at a portion of said sealing member for filling the liquid crystal into said space, a metal layer formed across the full width of the side surfaces of said substrates sandwiching said peripheral sealing member surrounding said filling port, and a solder layer applied onto said metal layer for sealing said filling port, said solder layer having an amount of 0.1 to 1.2mg/mm.sup.2.
A method of menufacturing a liquid crystal display device of the class comprising a pair of spaced parallel insulating substrates, at least one of the substrates being transparent, opposed electrodes formed on the opposing surfaces of said substrates, a peripheral sealing member for sealing the peripheries of said substrates and defining a space for accommodating a liquid crystal, and means for defining a filling port at a portion of said peripheral sealing member for filling the liquid crystal into said space, said method comprising the step of applying a single molten solder ball having a weight sufficient to form a solder seal having an amount of 0.1 to 1.2mg/mm.sup.2 across the full width of the side surfaces of said substrates sandwiching said peripheral sealing member surrounding said filling port, thus sealing the same.
