Abstract:
1. A method of manufacturing a display panel, comprising: a bonded body fabricating step of fabricating a bonded body having a first mother substrate, which is made of glass and in which a plurality of display regions are formed, a second mother substrate, which is made of glass and is positioned so as to face the first mother substrate, and in which a plurality of display regions are formed so as to overlap the display regions of the first mother substrate, and a sealant, which is provided in a frame shape between the first mother substrate and the second mother substrate so as to surround each of the display regions, and which bonds the first mother substrate to the second mother substrate; and a cutting step of forming a crack above at least one side of the sealant surrounding each of the display regions in each of outer surfaces of the first mother substrate and the second mother substrate of the bonded body, and cutting the bonded body into sections including the display regions, wherein the cutting step includes a first mother substrate cutting step of forming a crack above at least one side of the sealant surrounding each of the display regions in the outer surface of the first mother substrate of the bonded body, and then causing the crack to develop in a substrate thickness direction to cut the first mother substrate into sections including the display regions, a residual stress reducing step of reducing a residual stress of the sealant in the bonded body in which the first mother substrate has been cut, and a second mother substrate cutting step of forming a crack above at least one side of the sealant surrounding each of the display regions in the outer surface of the second mother substrate of the bonded body in which the residual stress of the sealant has been reduced, and then causing the crack to develop in the substrate thickness direction to cut the second mother substrate into sections including the display regions.
