Abstract

A method for manufacturing a display device includes checking a particle positioned between a display panel and a connecting member, irradiating a laser to an upper surface of the connecting member overlapping at least a part of the particle, removing the connecting member overlapping a region to which the laser is irradiated, removing the particle overlapping a region to which the laser is irradiated, and disposing a desiccant in a hole formed by removing the connecting member and the particle.

Claims (37)

1. A method for manufacturing a display device, the method comprising:

checking a particle positioned between a display panel and a connecting member, the display panel including pads spaced apart from each other and the connecting member being formed on the pads;

irradiating a laser to an upper surface of the connecting member overlapping at least a part of the particle;

removing the connecting member overlapping a region to which the laser is irradiated;

removing the particle overlapping a region to which the laser is irradiated; and

disposing a desiccant in a hole formed by removing the connecting member and the particle.

2. The method of claim 1 , wherein the particle includes a conductive material.

3. The method of claim 1 , further comprising:

determining whether the particle overlaps two adjacent pads among the pads after the checking of the particle.

4. The method of claim 3 , wherein the irradiating of the laser comprises irradiating the laser to the particle overlapping a space where the two adjacent pads are spaced apart from each other.

5. The method of claim 1 , further comprising:

disposing an adhesive member between the pads and the connecting member before the checking of the particle.

6. The method of claim 5 , wherein the particle is positioned between the connecting member and the adhesive member.

7. The method of claim 5 , wherein

the particle is positioned between the adhesive member and the display panel, and

the method further comprising removing the adhesive member overlapping a region to which the laser is irradiated.

8. The method of claim 7 , wherein the removing of the connecting member and the removing of the particle include:

removing the connecting member overlapping the region to which the laser is irradiated by irradiating the laser with a first output;

removing the adhesive member overlapping the region to which the laser is irradiated by irradiating the laser with a second output; and

removing the particle overlapping the region to which the laser is irradiated by irradiating the laser with a third output.

9. The method of claim 8 , wherein

the first output and the second output are identical, and

the first output is greater than the third output.

10. The method of claim 1 , further comprising:

injecting air into the hole formed by removing the connecting member and the particle after the removing of the connecting member and the removing of the particle.

11. The method of claim 1 , wherein the disposing of the desiccant includes spraying the desiccant to the hole.

12. The method of claim 11 , wherein the disposing of the desiccant includes filling the desiccant inside of the hole.

13. The method of claim 11 , further comprising:

irradiating an ultraviolet-ray to the desiccant after the disposing of the desiccant.

14. The method of claim 1 , further comprising:

checking whether the particle overlapping the region to which the laser is irradiated is removed; and

re-irradiating the laser when the particle is not removed.

15. The method of claim 1 , wherein the laser is a femtosecond laser.

16. The method of claim 1 , wherein

the display panel includes a first substrate and a second substrate facing the first substrate,

the pads are formed on side surfaces of the first and second substrates, and

the side surfaces of the first and second substrates and the upper surface of the connecting member are parallel to each other.
