A method of producing a display panel including substrates having an inner space therebetween surrounded by a sealing material and an outer space outside the inner space and one substrate includes an inner space structure part and an outer space structure part, the method includes a substrate deforming step of displacing a part of the outer space structure part toward another substrate to cause an end part of the inner space structure part near the part of the outer space structure part to be moved away from the other substrate, resulting in a part of the inner space structure part being warped to be away from the other substrate, a dividing step of dividing the substrates into portions configuring the inner space and the outer space, and a substrate bending step of bending the portion of the substrates configuring the inner space so that the one substrate projects outward.
