Abstract:
A method for manufacturing a flat display element provided with a pair of substrates opposed to each other across a given gap and including respective peripheral edge portions thereof stuck on each other with a sealant, comprising:preparing a pair of motherboards larger than the substrates; forming a display forming portion on each motherboard; locating the sealant on at least one of the motherboards so as to surround the peripheral edge portion of the display forming portion; locating, on end portions of the motherboard except corner portions of the motherboard, spacers for maintaining the gap between the two motherboards and a dummy sealant covering spacers, the sealant and the dummy sealant being formed individually of materials cured by the same method; locating, on the corner portions of the motherboard, end spacers for maintaining the gap between the two motherboards and a tacker covering the end spacers, the dummy sealant and the tacker being formed individually of materials cured by different methods; sticking the two motherboards on each other with the sealant, dummy sealant, spacers, end spacers, and tacker between the two; aligning the two stuck motherboards with each other; tacking the two motherboards to each other by curing the tacker after the aligning; finally bonding the two motherboards to each other by curing the sealant and dummy sealant after the tacking; and cutting out the substrates by cutting the two motherboards outside the sealant after the final bonding.
