Abstract

Provided are display panel, method of manufacturing the same, and frit composition used in the display panel. A display panel comprising: a first substrate, a second substrate facing the first substrate and a frit bonding the first substrate and the second substrate together, wherein the frit has an optical density of more than about 0.0683/μm for laser light of any one wavelength in a wavelength range of about 760 to about 860 nm.

Claims (16)

1. A display panel comprising:

a first substrate;

a second substrate facing the first substrate; and

a frit bonding the first substrate and the second substrate together,

wherein the frit has an optical density of more than about 0.0683/μm for laser light of any one wavelength in a wavelength range of about 760 to about 860 nm;

wherein when a maximum width of the frit is D, when the width of the frit in a region in which the frit contacts the first substrate is d1, when the width of the frit in a region in which the frit contacts the second substrate is d2, and wherein d1 is defined as a seal width of the frit, a ratio of the seal width of the frit to D is about 0.7 or more; and wherein d2 and D are substantially equal.

2. The display panel of claim 1 , wherein when a width of the frit in a region in which the frit contacts the first substrate is d1, when a width of the frit in a region in which the frit contacts the second substrate is d2, and when a smaller value of d1 and d2 is defined as a seal width of the frit, the seal width of the frit is about 420 to about 600 μm.

3. The display panel of claim 1 , wherein the frit comprises vanadium-based mother glass.

4. The display panel of claim 3 , wherein the frit comprises about 40 to about 50% by mole of V2O5.

5. The display panel of claim 3 , wherein the frit further comprises V2O4.

6. The display panel of claim 5 , wherein the frit is brownish in color.

7. The display panel of claim 3 , wherein the frit further comprises filler and a pigment which contains one or more materials selected from the group consisting of MnO, MnO2, and Mn3O4.

8. The display panel of claim 1 , wherein the frit comprises bismuth-based mother glass, and the frit has an optical density of about 0.1567/μm or greater.

9. The display panel of claim 8 , wherein the frit comprises filler and a pigment which contains one or more materials selected from the group consisting of MnO, MnO2, and Mn3O4.

10. The display panel of claim 9 , wherein content of the pigment is about 9.9 to about 11.01% by mole.

11. The display panel of claim 10 , wherein the frit comprises about 30 to about 45% by mole of Bi2O3.
