Abstract

Provided is a liquid crystal display including: a display panel which includes a lower panel including a thin film transistor, a pixel electrode connected to the thin film transistor, and a light blocking member; an upper panel facing the lower panel; and a liquid crystal layer positioned between the lower panel and the upper panel and including liquid crystal molecules. The display panel is a curved display panel which is curved on a first axis. The pixel electrode has long sides and short sides, and the long sides are arranged to be substantially parallel with a second axis perpendicular to the first axis.

First claim

What is claimed is:

1 . A liquid crystal display, comprising:
a display panel which includes a lower panel including a thin film transistor, a pixel electrode connected to the thin film transistor, and a light blocking member; an upper panel facing the lower panel; and a liquid crystal layer positioned between the lower panel and the upper panel and including liquid crystal molecules; wherein the display panel is a curved display panel which is curved on a first axis, and the pixel electrode has long sides and short sides, and the long sides are arranged to be substantially parallel with a second axis perpendicular to the first axis.

2 . The liquid crystal display of claim 1 , wherein:
the short sides of the pixel electrode are arranged to be substantially parallel with the first axis.

3 . The liquid crystal display of claim 1 , wherein:
the lower panel further includes a column spacer positioned on the light blocking member.

4 . The liquid crystal display of claim 3 , wherein:
the column spacer is formed of the same material as the light blocking member.

5 . The liquid crystal display of claim 1 , wherein:
the upper panel includes a common electrode, and the pixel electrode includes a plurality of domains in which tilted directions of the liquid crystal molecules are differently controlled.

6 . The liquid crystal display of claim 5 , wherein:
the pixel electrode includes stems which form a boundary between adjacent domains.

7 . The liquid crystal display of claim 6 , wherein:
the pixel electrode further includes a plurality of minute branches which extends in different directions in different domains.

8 . The liquid crystal display of claim 7 , wherein:
the stems include a first stem and a second stem which cross each other to form a cross, and the plurality of minute branches extends in different directions in four domains which are divided by the first and second stems.

9 . The liquid crystal display of claim 8 , wherein:
the first stem is arranged to be substantially parallel to the first axis, and the second stem is arranged to be substantially parallel to the second axis.

10 . The liquid crystal display of claim 8 , wherein:
the length of the first stem is larger than the length of the second stem.

11 . The liquid crystal display of claim 8 , wherein:
the common electrode includes an opening which faces at least one of the first and second stems and is formed in parallel with it.

12 . The liquid crystal display of claim 1 , wherein:
the thin film transistor is positioned between two pixel electrodes which are adjacent to each other in the first axial direction.

13 . The liquid crystal display of claim 1 , wherein:
a ratio of the short side to the long side of the pixel electrode is about 3:1.

14 . The liquid crystal display of claim 1 , wherein:
the lower panel further includes a color filter.

15 . The liquid crystal display of claim 1 , wherein:
the light blocking member is formed to cover a peripheral area of the pixel electrode.

16 . The liquid crystal display of claim 1 , wherein:
the column spacer includes a main column spacer and a sub column spacer, the main column spacer is higher than the sub column spacer.

17 . The liquid crystal display of claim 1 , wherein:
the display panel is a curved display panel which is further curved on the second axis.
