Method of producing display panels

A method of collectively producing display panels each having an outline a part of which is curved, the method comprising:

• a bonded substrate forming process of bonding substrates in a pair one of which has thin film patterns and forming a bonded substrate;
• a layering process of layering multiple bonded substrates via curing resin and curing the curing resin after the bonded substrate forming process, the curing resin containing:
• (A) a polyfunctional (meth)acrylate oligomer/polymer and/or a polyfunctional (meth)acrylate monomer,
• (B) aromatic mono(meth)acrylate not having a hydroxyl group, a carboxyl group, and an epoxy group and/or alicyclic mono(meth)acrylate not having a hydroxyl group, a carboxyl group, and an epoxy group,
• (C) a radical photopolymerization initiator,
• (D) a radical thermal polymerization initiator,
• (E) a polymerization accelerator, and
• (F) thermally expandable microcapsules,
• as a first agent containing at least the radical photopolymerization initiator and a second agent containing at least the radical thermal polymerization initiator;
• a grinding process of collectively grinding the substrates in a pair and the curing resin that are outside the thin film pattern on each of the bonded substrates that are layered on each other along the outline and collectively forming edge surfaces of the display panels each having the curved outline, the grinding process being performed after the layering process;
• and
• a separation process of separating each of the bonded substrates that are layered on each other from the curing resin after the grinding process.
