Abstract

A liquid crystal display according to an exemplary embodiment of the present invention includes a first display panel and a second display panel which are opposite to each other, a driving unit connection line which is formed in the first display panel, a driving circuit portion which is connected to the driving unit connection line, a backlight unit which is disposed so as to be adjacent to the first display panel, a polarizer which is disposed on a surface of the second display panel and overlaps the driving unit connection line and the driving circuit portion, and a reinforcement unit that overlaps the driving unit connection line, and the polarizer may be disposed on the reinforcement unit.

First claim

What is claimed is:

1. A liquid crystal display, comprising:
a first display panel and a second display panel disposed facing each other;
a driving unit connection line disposed on the first display panel;
a driving circuit portion electrically connected to the driving unit connection line;
a backlight unit disposed adjacent to the first display panel;
a polarizer disposed on a surface of the second display panel and overlapping the driving unit connection line and the driving circuit portion,
wherein a portion of the driving unit connection line does not overlap the second display panel, and
the polarizer overlaps the portion of the driving unit connection line not overlapping the second display panel.

2. The liquid crystal display of claim 1 , further comprising:
a reinforcement unit overlapping the driving unit connection line,
wherein the polarizer is disposed on the reinforcement unit.

3. The liquid crystal display of claim 2 , wherein:
the reinforcement unit overlaps the portion of the driving unit connection line not overlapping the second display panel.

4. The liquid crystal display of claim 3 , wherein:
a surface of the reinforcement unit is coplanar with a surface of the second display panel.

5. The liquid crystal display of claim 4 , wherein:
the reinforcement unit comprises an elastic material.

6. The liquid crystal display of claim 2 , wherein:
the reinforcement unit comprises an elastic material.

7. The liquid crystal display of claim 2 , wherein:
the backlight unit comprises:
a backlight assembly; and
a mold frame supporting the backlight assembly, and
a chassis unit is not disposed between the backlight unit and the first display panel.

8. The liquid crystal display of claim 1 , wherein:
the backlight unit comprises:
backlight assembly, and
a mold frame supporting the backlight assembly, and
no chassis unit is disposed between the backlight unit and the first display panel.

9. The liquid crystal display of claim 8 , wherein:
the mold frame comprises an opening,
a portion of light radiated from the backlight assembly is directly transmitted onto a first portion of the first display panel through the opening, and
a first display portion is disposed in the first portion of the first display panel.

10. The liquid crystal display of claim 9 , further comprising:
silver disposed on at least a portion of the first display portion.

11. The liquid crystal display of claim 1 , wherein:
the polarizer comprises a first region and a second region,
the second region of the polarizer is free of polarization ink,
the second region of the polarizer overlaps a second portion of the first display panel, and
a second display portion is disposed in the second portion of the first display panel.

12. The liquid crystal display of claim 2 , further comprising:
silver disposed on at least a portion of the second display portion.

13. The liquid crystal display of claim 1 , further comprising:
a touch panel disposed on the polarizer,
wherein the touch panel overlaps the driving unit connection line and the driving circuit portion.

14. A liquid crystal display, comprising:
a first display panel and a second display panel disposed facing each other;
a driving unit connection line disposed on the first display panel;
a driving circuit portion electrically connected to the driving unit connection line;
a backlight unit disposed adjacent to the second display panel; and
a polarizer disposed on a surface of the first display panel and overlapping the driving unit connection line and the driving circuit portion,
wherein a portion of the driving unit connection line does not overlap the second display panel, and
the polarizer overlaps the portion of the driving unit connection line not overlapping the second display panel.

15. The liquid crystal display of claim 14 , further comprising:
a reinforcement unit overlapping the driving unit connection line,
wherein the polarizer is disposed on the reinforcement unit.

16. The liquid crystal display of claim 15 , wherein:
the backlight unit comprises:
a backlight assembly; and
a mold frame supporting the backlight assembly, and
no chassis unit is disposed between the backlight unit and the first display panel.

17. The liquid crystal display of claim 14 , wherein:
the backlight unit comprises:
a backlight assembly; and
a mold frame supporting the backlight assembly, and
no chassis unit is disposed between the backlight unit and the first display panel.

18. A manufacturing method of a liquid crystal display, comprising:
forming a first display panel and a second display panel, the first display panel comprising a signal line formed in a pixel region, a driving unit connection line electrically connected to the signal line, and a driving circuit portion connected to the driving unit connection line;
forming a first polarizer on a surface of the first display panel;
coupling the first display panel and a backlight unit to each other;
washing the second display panel; and
forming a second polarizer on the second display panel,
wherein the second polarizer is formed so as to overlap the driving unit connection line and the driving circuit portion,
wherein the forming of the first display panel and the second display panel comprises forming a portion of the driving unit connection line so as not to overlap the second display panel, and
wherein the forming of the second polarizer comprising forming the second polarizer so as to overlap the portion of the driving unit connection line not overlapping the second display panel.

19. The manufacturing method of claim 18 , further comprising:
forming a reinforcement unit overlapping the driving unit connection line,
wherein the forming of the second polarizer comprises disposing the second polarizer on the second display panel and the reinforcement unit.

20. The manufacturing method of claim 19 , wherein:
the forming of the reinforcement unit comprises forming the reinforcement unit so as to overlap the portion of the driving unit connection line that does not overlap the second display panel.

21. The manufacturing method of claim 20 , wherein:
a surface of the reinforcement unit is coplanar with a surface of the second display panel.

22. The manufacturing method of claim 21 , wherein:
the reinforcement unit comprises an elastic material.

23. The manufacturing method of claim 19 , wherein:
