Organic light emitting display device having a triple dam structure
Disclosed is an organic light emitting display device including a dam structure disposed in a non-display area of a substrate and an alignment mark disposed outside the dam structure. The alignment mark is not covered by, and does not overlap with, the dam structure, because the alignment mark is disposed outside the dame structure. Thus, a scribing process may be performed smoothly.
1. An organic light emitting display device comprising:
a substrate including an active area and a non-display area provided outside the active area;
a dam structure in the non-display area of the substrate; and
a first alignment mark outside the dam structure in the non-display area of the substrate,
wherein
the dam structure comprises a first dam structure arranged in a first direction, a second dam structure arranged in a second direction, and a third dam structure connected to each of the first dam structure and the second dam structure at an incline, and
the first alignment mark is disposed outside the third dam structure.
2. The organic light emitting display device of claim 1 , wherein
the first dam structure and the second dam structure are arranged in parallel with an outermost line of the active area in the first direction and an outermost line of the active area in the second direction, respectively, and
the third structure is arranged apart from, and at an angle to, a vertex at which the outermost line of the active area in the first direction meets the outermost line of the active area in the second direction.
3. The organic light emitting display device of claim 1 , wherein
the first dam structure comprises a first sealant, a first outer dam bank disposed on an outer side of the first sealant, and a first inner dam bank disposed on an inner side of the first sealant,
the second dam structure comprises a second sealant, a second outer dam bank disposed on an outer side of the second sealant, and a second inner dam bank disposed on an inner side of the second sealant,
the third dam structure comprises a third sealant, a third outer dam bank disposed on an outer side of the third sealant, and a third inner dam bank disposed on an inner side of the third sealant,
one end of the third sealant is connected to the first sealant, and the other end of the third sealant is connected to the second sealant,
one end of the third outer dam bank is connected to the first outer dam bank, and the other end of the third outer dam bank is connected to the second outer dam bank, and
one end of the third inner dam bank is connected to the first inner dam bank, and the other end of the third inner dam bank is connected to the second inner dam bank.
4. The organic light emitting display device of claim 3 , wherein a distance between the third inner dam bank and a vertex at which an outermost line of the active area in the first direction meets an outermost line of the active area in the second direction is equal to or greater than a distance between the first inner dam bank and the outermost line of the active area in the first direction or the distance between the second inner dam bank and the outermost line of the active area in the second direction.
5. The organic light emitting display device of claim 3 , wherein at least one of the third outer dam bank and the third inner dam bank has a concave-convex structure.
6. The organic light emitting display device of claim 1 , wherein the first alignment mark is disposed on an extension line of the first dam structure or the second dam structure.
7. The organic light emitting display device of claim 1 , wherein the first alignment mark is disposed inward from an extension line of the first dam structure or the second dam structure.
8. The organic light emitting display device of claim 1 , wherein
the substrate comprises a pad area in the non-display area, and
a second alignment mark is further provided in the pad area.
9. The organic light emitting display device of claim 8 , wherein
the dam structure is not disposed in the pad area.
10. The organic light emitting display device of claim 1 , wherein the third dam structure has a rectilinear structure.
11. The organic light emitting display device of claim 1 , wherein the third dam structure has a curve structure.
12. The organic light emitting display device of claim 11 , wherein the curve structure is convex in an outer direction.
13. The organic light emitting display device of claim 11 , wherein the curve structure is convex in an inner direction.
14. The organic light emitting display device of claim 1 , wherein
the substrate comprises a pad area in the non-display area, and
a second alignment mark is disposed outside the third dam structure such that the second alignment mark does not overlap with the pad area.
15. The organic light emitting display device of claim 14 , wherein
the dam structure is not disposed in the pad area.
16. The organic light emitting display device of claim 1 , further comprising:
a second substrate; and
a filler disposed between the first substrate and the second substrate, and extending from the active area to an inner side of the dam structure.
