Abstract:
1. A method of manufacturing a flat panel display device, the method comprising: 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 of the walls respectively surrounds one of the emission units; simultaneously irradiating a laser beam to a plurality of first 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 unit display devices, wherein each of the walls surrounding an emission unit comprises the first wall portions, which extend in the first direction, and second wall portions, which extend in the second direction, wherein the laser beam is simultaneously irradiated onto each of the first wall portions aligned in a row in the first direction, and simultaneously irradiated to at least a portion of the second walls.
