Display panel, method of manufacturing the same, and FRIT composition used in the display panel
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.
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.
