Method of manufacturing flat panel display device
First Claim
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.

Abstract
A method of manufacturing a flat panel display device is disclosed. In one embodiment, the method includes: i) forming a plurality of light emitting units on a first substrate, each of the plurality of light emitting units including a light emitting element, ii) providing a second substrate, iii) placing glass frits between the first and second substrates, iv) radiating a first laser beam, having a first intensity, on one of the first and second substrates, wherein the first laser is configured to melt the grass frits and combine the first and second substrates and v) radiating a second laser beam, having a second intensity, on the first irradiated region so as to anneal the first or second substrate, wherein the second intensity is different from the first intensity. According to one embodiment, the substrate cutting quality can be simply improved.

14. A flat panel display device manufactured by a method, the method comprising:
-
providing first and second substrates, wherein a glass fit is formed on one of the substrates; radiating, during a period of time, a first laser beam which is configured to melt the frit and combine the first and second substrates; and radiating, after the period of time, a second laser beam toward at least one of the first and second substrates, on the area where the first laser beam has been radiated, so as to anneal the first or second substrate, wherein the intensity of the first laser beam is different from that of the second laser beam, and wherein the second laser beam is radiated in a substantially opposite direction to the direction of radiation of the first laser beam. - View Dependent Claims (15, 16, 17)

18. A method of manufacturing a flat panel display device, the method comprising:
-
providing a glass frit between first and second substrates; radiating a first laser beam, having a first intensity, on one of first and second substrates so as to melt the glass frit and combine the first and second substrates; and radiating a second laser beam, having a second intensity, on the first radiated region, so as to anneal the first or second substrate, wherein the second intensity is substantially less than that of 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.
