Abstract

A liquid crystal display, including a display panel including an upper panel, a lower panel, and a liquid crystal layer interposed therebetween, the display panel being defined by a display area and a peripheral area, the display panel including a sealing member enclosing the display area and in the peripheral area, the upper panel including a light blocking member in the peripheral area, the light blocking member including a well.

First claim

What is claimed is:

1. A liquid crystal display, comprising:
a display panel including an upper panel, a lower panel, and a liquid crystal layer interposed therebetween,
the display panel being defined by a display area and a peripheral area, the display panel including a sealing member enclosing the display area and in the peripheral area,
the upper panel including a light blocking member in the peripheral area and an alignment layer, the light blocking member including one or more wells, wherein at least one well of the one or more wells overlaps the alignment layer, and
the upper panel including a common electrode, the common electrode overlapping the one or more wells,
wherein at least one well of the one or more wells is between the display area and the sealing member so as to not overlap or contact the sealing member.

2. The liquid crystal display as claimed in claim 1 , wherein the well overlaps the sealing member.

3. The liquid crystal display as claimed in claim 1 , wherein the well is between the display area and the sealing member.

4. The liquid crystal display as claimed in claim 1 , wherein the well encloses the display area.

5. The liquid crystal display as claimed in claim 4 , wherein the upper panel includes a plurality of wells parallel to each other, and an outermost well is inside an outermost part of the sealing member.

6. The liquid crystal display as claimed in claim 5 ,
wherein the alignment layer is not external to the outermost well.

7. The liquid crystal display as claimed in claim 4 , wherein the well is continuous at a circumference of the display area.

8. The liquid crystal display as claimed in claim 4 , wherein the well is disconnected at at least a portion of a circumference of the display area.

9. The liquid crystal display as claimed in claim 1 , wherein the lower panel includes a light blocking member overlapping the well.

10. The liquid crystal display as claimed in claim 1 , wherein the lower panel includes an opaque metal layer overlapping the well.

11. The liquid crystal display as claimed in claim 1 , wherein the well has a linear or quadrangular shape, or a mix thereof.

12. The liquid crystal display as claimed in claim 1 ,
wherein the alignment layer is not external to the well.

13. The liquid crystal display as claimed in claim 1 , wherein the display panel is a curved display panel.

14. The liquid crystal display as claimed in claim 1 , wherein the lower panel includes a color filter and a light blocking member in the display area.

15. The liquid crystal display as claimed in claim 14 , wherein the lower panel includes a column spacer on the light blocking member and including a same material as the light blocking member.

16. The liquid crystal display as claimed in claim 14 , wherein the lower panel includes at least one barrier in the peripheral area.

17. The liquid crystal display as claimed in claim 16 , wherein the barrier includes a same material as the color filter or the light blocking member.

18. The liquid crystal display as claimed in claim 16 , wherein the barrier overlaps the sealing member.

19. The liquid crystal display as claimed in claim 16 , wherein the barrier is between the display area and the sealing member.
