Abstract: A method for manufacturing a display panel includes forming a circuit element layer including a transistor on a plurality of cell areas of a first working substrate. Each of the cell areas includes a hole area on which at least one first sub-opening groove on which the circuit element layer is not formed is located. The method further includes forming a display element layer including a light emitting element on the plurality of cell areas, removing at least one inorganic layer of the display element layer formed in the first sub-opening groove by stamping to define a second sub-opening groove, coupling the first working substrate to a second working substrate to define a working panel, and cutting the working panel into portions corresponding to the plurality of cell areas.
