Abstract:
1. A method of manufacturing a flat panel display device, the method comprising: forming a plurality of light emitting units on a first substrate, each of the plurality of light emitting units including a light emitting element; providing a second substrate; placing glass frits between the first and second substrates; radiating a first laser beam, having a first intensity, on one of the first and second substrates, so as to melt the glass frits and combine the first and second substrates; and radiating a second laser beam, having a second intensity, on the area where the first laser beam has been radiated, so as to anneal the first or second substrate, wherein the second intensity is different from the first intensity, and wherein the second laser beam is radiated in a substantially opposite direction to the direction of radiation of the first laser beam.
