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.

Abstract: A method of manufacturing a display apparatus includes: preparing a substrate including a display area and a sensor area arranged in the display area; forming first counter electrodes on the substrate so that the first counter electrodes are spaced apart from one another in the sensor area to have a first pattern; depositing second counter electrodes having a second pattern different from the first pattern to be spaced apart from one another in the sensor area; and arranging a component to correspond to the sensor area.
