To minimize stress variations applied to mother glasses when a glass sealing material is melted via a laser to combine the mother glasses, a method of manufacturing a flat panel display device includes providing a plurality of emission units between a first substrate and a second substrate, wherein the first substrates faces the second substrate and each emission unit forms a unit display device; providing a plurality of walls between the first substrate and the second substrate, wherein each wall respectively surrounds one of the emission units; irradiating a laser beam onto the walls, wherein the laser beam is simultaneously irradiated to wall portions aligned in a row in a first direction; scanning the laser beam in a second direction, wherein the second direction is different from the first direction to irradiate other wall portions of the plurality of walls; and cutting the first and second substrates to obtain individual display devices. |
