Seal pattern for liquid crystal display device including inner seal with first and second openings
View Patent ↗A seal pattern for a liquid crystal display device includes a substrate having an active area and a non-active area, a main seal pattern having an injection hole arranged in a boundary between the active and non-active areas, and first, second, and third dummy-seal patterns in the non-active area that are arranged along a same direction as a portion of the main seal pattern having the injection hole and spaced apart from each other. The first and second dummy-seal patterns have first and second openings corresponding to opposite ends of the injection hole. The third dummy-seal pattern has third, fourth, and fifth openings arranged alternatively in correspondence with the first and second openings.
1. A seal pattern of a liquid crystal display device, comprising:
a display area;
a main seal adjacent to the display area;
an injection hole arranged within a portion of the main seal;
an outer seal spaced apart from and arranged substantially parallel to the portion of the main seal; and
at least one inner seal arranged between the outer seal and the main seal, the at least one inner seal being arranged substantially parallel to the portion of the main seal, wherein the at least one inner seal comprises first and second openings, wherein a portion of the at least one inner seal between the first and second openings is substantially symmetric about a centerline of the injection hole.
2. The seal pattern of a liquid crystal display device according to claim 1 , further comprising extended seals arranged at opposing ends of the outer seal, wherein the extended seals are substantially perpendicular to the portion of the main seal.
3. The seal pattern of a liquid crystal display device according to claim 2 , wherein the extended seals are spaced apart from the at least one inner seal and the main seal.
4. The seal pattern of a liquid crystal display device according to claim 1 , wherein the portion of the at least one inner seal between the first and second openings is substantially the same width as the injection hole.
5. The seal pattern of a liquid crystal display device according to claim 1 , further comprising third, fourth, and fifth openings arranged within the outer seal.
6. The seal pattern of a liquid crystal display device according to claim 5 , wherein each of the first and second openings comprises a first end and a second end opposite the first end, wherein a centerline of the third opening is arranged proximate one of the first and second ends of the first openings, wherein a centerline of the fourth opening is arranged proximate the other of the first and second ends of the first openings and proximate one of the first and second ends of the second openings, and wherein a centerline of the fifth opening is arranged proximate the other of the first and second ends of the second openings.
7. The seal pattern of a liquid crystal display device according to claim 5 , wherein a centerline of one of the third, fourth, and fifth openings is substantially aligned with the centerline of the portion of the at least one inner seal between the first and second openings.
8. The seal pattern of a liquid crystal display device according to claim 5 , wherein a sum of the widths of the third, fourth, and fifth openings is substantially equal to a sum of the widths of the first and second openings.
